Brankman/Jeff Bachhuber Date: December 14, 2001 Verifier: Scott C. Lindvall 1.0 PURPOSE This Calculation Package describes and documents the kinematic analyses performed to identify modes of potential rock slope failure in the proposed cutslopes at the ISFSI site. These analyses incorporate the extensive discontinuity data collected from the ISFSI study area (William Lettis & Associates, Inc., 2001, Diablo Canyon ISFSI Data Reports B, E and F) to help identify potential rock slope failure conditions in the proposed excavation cutslopes (Figure 22-1) and in the existing roadcuts on the transport route along Reservoir Road (Figure 22-2). The purpose of these analyses is to evaluate the potential for shallow failures (less than 20 feet) in the cutslope walls and road cut. The results are used in analyzing mitigation measures addressed in Calculation Package GEO.DCPP.01.08 and in analyzing the stability of rock wedges, addressed in Calculation GEO.DCPP.01.23. It does not address deep-seated global slope stability of the hillside above the ISFSI site, a topic which is analyzed in Calculation Packages GEO.DCPP.01.24 through 26. The specific areas included in the analyses are the Westcut cutslope, the Backcut cutslope, the Eastcut cutslope, and two portions of the transport route along Reservoir Road. The analyzed cutslopes are shown on Figures 22-1 and 22-2.GEO.DCPP.01.22 Rev. 1 Page 5 of 168 December 14, 2001 Calculation 52.27.100.732, Rev. 0, Attachment A, Page _1 of 79
2.0 BACKGROUND
Stereographic projections of fracture data are tools commonly used to predict the types of discontinuity-controlled rock slope failures that are possible for given cutslope configurations and rock friction angles. Kinematic analyses of discontinuity data allow for the recognition of potential rock slope stability failures by examining the geometric relationships between discontinuity surfaces and the rock face. The technique is simple and easily performed, and the effects of various rock friction angles and different rock cutslope configurations are readily seen. Kinematic analyses consider three primary failure modes: (1) topple failure of rock blocks and slabs, (2) planar sliding of rock on a single discontinuity or single discontinuity set, and (3) wedge sliding of rock along the intersection of two discontinuities. Other modes of slope failure, such as rotational slump failures, are not considered. Topple failures occur as blocks or slabs, which are bounded by discontinuities that dip steeply into the face at angles such that the center of mass falls outside the toe of the block and causes outward rotation and topple out of the cut face. Planar sliding failures occur when a rock mass slides along a single, optimally-oriented surface that dips out of the slope face. Wedge failures involve block sliding along two favorably oriented intersecting fractures in the direction of the plunge of the intersection line. Each of these failure scenarios is examined through a separate kinematic analysis. In general, several conditions must be met for kinematic instability. For toppling-type failures, discontinuities must be subparallel to, and dip steeply into, the rock face. For sliding-mode failures (planar and wedge sliding), two conditions must be met. First, the discontinuity surface (or intersection line between discontinuities) must daylight in the cutslope, i.e. the discontinuities must dip in the direction of the cutslope and be less steep than the cutslope angle. Second, the discontinuities (or discontinuity intersections) must dip at greater than the rock friction angle (Wyllie, 1992). If these criteria are not met, GEO.DCPP.01.22 Rev. 1 Page 6 of 168 December 14, 2001 Calculation 52.27.100.732, Rev. 0, Attachment A, Page 0- of 79 failure of the rock slope by sliding along discontinuities is resisted by adjacent rock blocks, and thus is not kinematically possible.
3.0 INPUTS
Discontinuity data (joints, faults, and bedding) collected from rock outcrops, exploratory trenches, roadcuts, and boreholes were used as the basis for the kinematic stability analyses. These data are presented in William Lettis & Associates, Inc. (2001), Diablo Canyon ISFSI Data Reports B, E, and F. Every discontinuity measurement from the test trenches at the ISFSI site was used in the kinematic analyses. Discontinuity data from boreholes were taken from the geophysical image logs; however, only the discontinuities that were confirmed by at least two geologists in order to verify the presence and type of discontinuity and the accuracy of the orientation were included. The input files containing the discontinuity data used in each analysis are included in Attachment
- 1. The joint and fault data are identical to those shown in Table 21-7, which were used to create the rose diagrams in Calculation Package GEO.DCPP.01.21.
For the kinematic analyses, bedding data was included with the joint and fault data. Friction angles used for the kinematic analyses were obtained from direct shear testing of fractures and bedding planes; these data are presented in William Lettis & Associates, Inc. (2001), Diablo Canyon ISFSI Data Report I, and in Calculation Package GEO.DCPP.01.20. The geometry of the ISFSI excavation and cutslopes is taken from drawing PGE-009-SK-001, transmitted to Geosciences on September 27, 2001 (Page, 2001). The analyses use a 70' angle for the cutslope walls, as shown in the drawing.
4.0 ASSUMPTIONS
The following assumptions were made for the kinematic analyses: GEO.DCPP.01.22 Rev. I Page 7 of 168 December 14, 2001 Calculation 52.27.100.732, Rev. 0, Attachment A, Page c. of 79 1. The potential shallow rock slope failures are controlled primarily by laterally persistent discontinuities that bound intact rock blocks. Discontinuities in the ISFSI study area are observed generally to be continuous over I to 3 feet and, in places, up to about 14 feet, and intersect to form discrete rock blocks of similar dimensions (William Lettis & Associates, Inc. (2001), Diablo Canyon ISFSI Data Report F). Therefore this assumption is realistic for these dimensions.
- 2. The shear strength of the fractured rock mass is controlled only by the basal rock friction angle of the discontinuities.
This is a conservative assumption because other factors that may impact shear strength, such as cohesion, asperity interlocking, or the presence of intact rock bridges across discontinuities, are not considered in this analysis.
- 3. Rock friction angle is assumed to be 28'. This value is based on direct shear laboratory testing of joints (William Lettis & Associates, Inc. (2001), Diablo Canyon ISFSI Data Report I) and the Barton criterion analyses (see Calculation Package GEO.DCPP.01.20).
The value chosen is considered a conservative value, because it is the near lower-bound of the straight line fits to the mean Barton envelopes for all discontinuity types. 4. Only the geometric relationships between the discontinuities and the cutslope are used in the analyses. The kinematic analyses assume no rock reinforcement to the slope. External forces, such as seismic loads and hydrostatic pressures, are not considered in the kinematic analyses. These factors increase the risk of slope failure identified in the kinematic analyses, but do not affect the analysis. These factors are considered in Calculation Package GEO.DCPP.01.23. GEO.DCPP.01.22 Rev. 1 Page 8 of 168 December 14, 2001 Calculation 52.27.100.732, Rev. 0, Attachment A, Page Lt of 79 5.0 METHOD The step-by-step methodology used for the kinematic analyses for each of the three cutslopes (Eastcut, Backcut, and Westcut) and the existing road cuts on the transport route along Reservoir Road is listed below: I. Compilation of discontinuity data from road cuts, trenches and borings near the slope being analyzed;
- 2. Development of stereographic projections of discontinuity data using the computer program DIPS (Rocscience, 1999), and identification of major discontinuity sets; and 3. Analyses of topple, planar sliding, and wedge sliding hazards.
Step 1 Discontinuity data were collected from road cuts, exploratory trenches and boreholes throughout the ISFSI study area. Details on the collection of these data are presented in William Lettis & Associates, Inc. (2001), Diablo Canyon ISFSI Data Reports B, E and F. For each wall of the proposed cut and for the roadcut, the data set from nearby trenches, borings, and roadcut were compiled to form distinct data sets for the analyses (Figures 22-1 and 22-2). The cutslope-specific data sets enable the evaluation to focus on local differences in discontinuity geometry, and identification of potential failure modes specific to each cutslope wall. Each discontinuity was classified in the field as either a joint, fault, or bedding surface, and this classification was carried into the DIPS input file. The DIPS input files are included in Attachment
- 1. Step 2 For each cutslope and road cut segment, the discontinuity data from the appropriate trenches, boreholes, and outcrops are plotted on an equal angle stereonet.
As described above, the plot shows discontinuities defined by discontinuity type (joint, fault, bedding).GEO.DCPP.01.22 Rev. 1 Page 9 of 168 December 14, 2001 Calculation 52.27.100.732, Rev. 0, Attachment A, Page k\ of 79 After plotting the data, sets of discontinuities were defined based on contouring and clustering of similar orientations. Only fracture groups that show well-defined clustering, on the basis of the scatter plots and the contour plots of the data, are grouped as discontinuity sets. Attributes of each defined discontinuity set, such as average orientation and variability to two standard deviations, are calculated by the DIPS software. Step 3 After defining the discontinuity sets, analyses for each mode of potential failure was performed. The procedure for each analysis is briefly described below. Topple failure -Topple failure of rock blocks is possible when discontinuities strike within about 300 of the cutslope, and dip steeply into the slope. On the stereographic projection, the pole to the discontinuity must fall within 30' to the dip direction of the cutslope, and must plot above a line inclined at an angle equivalent to the friction angle above the cutslope to be considered to have a potential of topple failure (blue-shaded area in Figure 22-3A) (Rocscience, 1999). Planar sliding failure -In order for planar sliding to occur, discontinuities must be present that strike within about 200 of the cutslope, and which dip at a shallower angle than the cutslope but steeper than the rock friction angle (Wyllie, 1992). On the stereographic projection, the pole to the discontinuity must fall within the daylight envelope of the cutslope but outside the rock friction cone to be considered to have a potential for planar sliding (blue-shaded area in Figure 22-3B). Wedge sliding failure -Wedge sliding of rock blocks occurs when the intersection line between two discontinuities plunges in the direction of the cut face at an angle steeper than the rock friction angle but less steep than the angle of the cutslope (Wyllie, 1992). On the stereographic projection, the line of intersection between two discontinuities sets plots as a point. This point must fall outside the cutslope great circle but within the rock friction cone to be considered to have the potential for wedge sliding GEO.DCPP.01.22 Rev. I Page 10 of 168 December 14, 2001 Calculation 52.27.100.732, Rev. 0, Attachment A, Page L1, of 79 (blue-shaded area in Figure 22-3C). Note that the rock friction cone in this analysis is counted in from the edge of the stereonet instead of out from the center, which is the reverse of the analysis for planar sliding; this is done because this analysis uses the great circles instead of the poles to assess the hazard (Rocscience, 1999). 6.0 SOFTWARE Fracture data visualization and kinematic analyses were performed using DIPS, v. 5.041 (Rocscience, 1999) on a DELL Dimension model XPS desktop computer running the Microsoft Windows 98 operating system. The software was purchased by and is licensed to William Lettis & Associates, Inc. (WLA), and all analyses were performed by WLA. The program has not been modified from the version purchased from Rocscience. Data tabulation, visualization, and kinematic analyses were performed using standard DIPS functions. The following program items were also identified as part of the verification process: a) program name: DIPS b) program version: 5.041 c) program revision: not applicable d) computer platform compatibility: Windows 98 e) program capabilities and limitations: The program performs kinematic stability analyses by plotting discontinuity data on stereonets, then analyzing if the data meet the requirements for stability in three failure modes: toppling, planar sliding, and wedge sliding. f) program test cases: described in Attachment

- 3. 7.0 ANALYSIS Separate analyses were performed for each of the three cutslopes in the ISFSI excavation and the two reaches of the transport route on Reservoir Road. Only data from nearby road cuts, trenches and borings were used in the analyses for each cutslope.
Trenches, borings, and roadcuts used in each analysis are shown in Figure 22-1. Discontinuity data used in the analyses are shown in the input files presented in Attachment
- 1. Summaries of the discontinuity sets are included in Table 22-1. Westcut Data from trenches T- I1 and T-18, borings 01-A, 01-B, 01-H, and discontinuity survey DS-1 were included in the analyses for the Westcut. A total of 211 discontinuity measurements were included in this data set (Attachment 1). The stereographic plots show clustering of discontinuities into four sets (Figure 22-4): (1) a WNW striking, steeply dipping set; (2) a NNW striking, steeply SSW dipping set; (3) a WNW to W striking, steeply N dipping set; and (4) a NW striking, shallowly dipping set. The remainder of the discontinuities are distributed throughout the stereonet without clear clustering, representing fractures with orientations not corresponding to a well-defined set.GEO.DCPP.01.22 Rev. 1 Page 12 of 168 December 14, 2001 Calculation 52.27.100.732, Rev. 0, Attachment A, Page _%of 79 Backcut Data from trenches T-3, T-4, T-5, T-6, T- 11, T-12, T-18, and T-20, discontinuity survey DS-1 and borings OOBA-2, 01-F, and 01-H were included in the analyses for the Backcut.
A total of 421 discontinuity measurements were included in this data set (Attachment 1). The data show clustering of discontinuities into four groups (Figure 22-5): (1) a N to NNW striking, steeply dipping set; (2) a NW striking, moderately steeply SW dipping set; (3) a WNW striking, steeply dipping set; and (4) a NW striking, shallowly SW dipping to flat set. The remainder of the discontinuities are distributed throughout the stereonet without clear clustering, representing fractures with orientations not corresponding to a well-defined set. Eastcut Data from trenches T-3, T-4, T-20, and T-21, and borings OOBA-2, 0l-E, and 01-G were included in the analyses for the Eastcut. A total of 167 discontinuities were included in this data set (Attachment 1). The data show discontinuities grouping into four clusters: (1) a NNE striking, steeply dipping set (Figure 22-6); (2) a NW striking, moderately steeply SW dipping set; (3) a NW striking, shallowly dipping to flat set; and (4) a W striking, steeply N dipping set. The remainder of the discontinuities are distributed throughout the stereonet without clear clustering, representing fractures with orientations not corresponding to a well-defined set. Transport Route Cutslopes Data from road cuts along Reservoir Road were included for the analyses of rock slopes along the Transport Route. A total of 37 discontinuity measurements were collected and included in this data set (Attachment 1). Two portions of the transport route were considered: the north-trending portion (stations 43+00 to 46+00), which is inclined at 50', and the northwest-trending portion (stations 35+00 to 43+00), which is inclined at 300. Each transport route analysis was performed using the entire discontinuity data set from the roadcut (37 measurements). The data show discontinuities grouping into three clusters (Figures 22-7 and 22-8): (1) a NW striking, steeply dipping set; (2) a NE striking, moderately S dipping set; and (3) a ENE striking, moderately N dipping set.GEO.DCPP.01.22 Rev. I Page 13 of 168 December 14, 2001 Calculation 52.27.100.732, Rev. 0, Attachment A, Page \& of 79 8.0 RESULTS Figures 22-4 through 22-6 show the output of the kinematic analyses for each wall of the proposed ISFSI cutslope. Figures 22-7 and 22-8 show the analyses for the transport route along Reservoir Road. Westcut Analyses of the Westcut are shown in Figure 22-4. The Westcut shows a high potential for topple failure. The majority of discontinuity set 2, as well as some fractures from set 1, plot within the zone of potential failure for toppling. However, analyses of planar and wedge sliding failures show low to very low potential, respectively, for these modes of failure in the western slope, as very few discontinuities (and none belonging to any of the defined sets) fall within the failure envelope for planar sliding, and none of the discontinuity intersections fall within the failure envelope for wedge sliding failure. Thus the only identified significant failure mode for the southwestern cutslope is topple failure. It should be noted that a portion of the southwestern cutslope will be infill, and, as such, the failure mode identified above is not applicable in these fill slopes. Backcut Kinematic analyses of the Backcut are shown in Figure 22-5. The slope shows low potential for toppling failure, as only a few random discontinuities plot within this failure envelope. Planar sliding failure represents a low- to moderate-potential, as a few discontinuities from sets 1 and 2, as well as a number of random discontinuities, plot within the planar sliding failure envelope. Potential exists for wedge sliding along the intersection line of discontinuity sets 2 and 3, while another intersection (1 and 3) plots outside but relatively close to the failure envelope and should be considered a potential hazard, given that these lines represent the average orientation of the set and that there is a scatter of orientations around this mean. Thus, there is a high potential for wedge failure and minor planar sliding failure on the Backcut.GEO.DCPP.01.22 Rev. 1 Page 14 of 168 December 14, 2001 Calculation 52.27.100.732, Rev. 0, Attachment A, Page L- of 79 Eastcut Kinematic analyses of the Eastcut are shown in Figure 22-6. The slope shows low potential for toppling failure, as only a few random discontinuities plot within this failure envelope. There is a moderate to high potential for planar sliding failure, as numerous discontinuities from discontinuity set 2 as well as some random discontinuities plot within the planar sliding failure envelope. Potential also exists for wedge sliding along the intersection lines between discontinuity sets 1 and 2 and between sets 2 and 4; though these intersections plot very close to the failure envelope, these lines represent the average orientation of the set and there is a scatter of orientations around this mean. Thus, there is a moderate to high potential for planar sliding and a moderate to high potential for wedge sliding failures along the Eastcut. Transport Route Cutslopes Kinematic analyses of the transport route cutslopes are shown in Figure 22-7 and 22-8. The north-trending slope shows moderate potential for toppling failure, as a large portion of set 1 plot within this failure envelope. There is low potential of planar sliding failure, and very low potential for wedge sliding failure. The northwest-trending slope shows low potential for all three failure modes. This is because of the very low inclination of this slope. Thus, the only the potentially significant failure mode is for topple failures along the transport route cutslopes.
9.0 CONCLUSION
S Stereographic kinematic analyses of discontinuity-controlled shallow rock slope failures in the proposed ISFSI excavation cutslopes show that each of the three cutslopes are prone to potential shallow rock stability hazards, but failure modes and potential for failure vary between slopes. The results are summarized in Table 22-2. The Westcut will primarily be prone to toppling failure of rock blocks into the cut along steeply dipping discontinuities. The Backcut has a high potential of wedge failures along two discontinuity sets, a minor potential of planar sliding, and low potential of topple failure. The Eastcut is prone primarily to planar wedge sliding, with little topple failure hazard.GEO.DCPP.01.22 Rev. 1 Page 15 of 168 December 14, 2001 Calculation 52.27.100.732, Rev. 0, Attachment A, Page 11 of 79 The transport route exhibits a low potential for rock topple, planar slide, and wedge sliding. These results will be used in the psuedostatic stability analyses of potential wedge failures (Calculation Package GEO.DCPP.01.23). Specific engineering measures will be required to mitigate the hazards associated with these potential failures.

The data has been collected by a geologist working on a single rock face above the first bench in a young open pit mine..m position Local bench slopes Overall pit slope (45 degrees)The rock face above the current floor of the existing pit has a dip of 45 degrees and a dip direction of 135 degrees.
The current plan is to extend the pit down at an overall angle of 45 degrees. This will require a steepening of the local bench slopes, as indicated in the figure above.GEO.DCPP.0 1.22 Rev. 1 U-w U U I! ..inI I II I; I: I..

In the above figure, you will notice that a great circle has been added to the plot, representing the pit slope. Planes are added to stereonet plots with the Add Plane option, as described below. Add Plane Before we add the plane, let's change the Convention. In DIPS, orientation coordinates can be displayed in either Pole Vector (Trend/Plunge) format, or Plane Vector format. Right now we want to use the Plane Vector Convention, which for this file is DIP/DIPDIRECTION, since this is the Global Orientation Format.GEO.DCPP.01.22 Rev. 1 57 Look closely at the data clustering and the data TYPE. Note the clustering of bedding features and the two dusters of shear features. These may behave very differently from similarly oriented joints or extension fractures, and should be considered separately. ptit N- --1, '. "-- 7.

A useful rule of thumb is that any cluster with a maximum concentration of greater than 6% is very significant. 4-6% represents a marginally significant cluster. Less than 4% should be regarded with suspicion unless the overall quantity of data is very high (several hundreds of poles).

- Introduction
- DIPS is a program designed for the interactive analysis of orientation based geological data. The program is a tool S* kit capable of many different applications and is designed both for the novice or occasional user, and for the S-.
user of stereographic projection who wishes to utilise more advanced tools in the analysis of geological data.
- DIPS allows the user to analyse and visualise structural data following the same techniques used in manual *stereonets.
In addition, many computational features are available, such as statistical contouring of orientation
- clustering, mean orientation calculation and qualitative and quantitative feature attribute analysis.
DIPS has been designed for the analysis of features related to the engineering analysis of rock structures, however, the free format of the DIPS data file permits the "* a analysis of any orientation based data. S.Aboutthis Manual This manual consists of the following tutorials:
- 1. Two basic tutorials, to get new users acquainted with -basic features of the program: .Quick Tour of DIPS ) Creating a DIPS File 2. Two advanced tutorials, to show how DIPS can be used for various types of analyses, which may not -.have been obvious without illustration:

The format of these orientation coordinates can be toggled with the Convention option in the Setup menu: " If the Convention is Pole Vector, the coordinates will be in Trend / Plunge format, and represent the cursor (pole) location directly. This is the default setting. " If the Convention is Plane Vector, the coordinates will correspond to the Global Orientation Format of the current document (eg. Dip/DipDirection, Strike/DipRight, Strike/DipLeft), and represent the PLANE corresponding to the cursor (pole) location. TIP- the Convention can be quickly toggled by clicking on the box in the Status Bar to the left of the coordinate display, with the LEFT mouse button. This is the quickest and most convenient way of toggling the Convention. The Convention also affects the format of certain data listings in DIPS (eg. the Major Planes legend, the Edit Planes and Edit Sets dialogs), and the format of orientation data input for certain options (eg. Add Plane and Add Set Window dialogs). Finally note that in DIPS, poles are ALWAYS plotted using the Trend and Plunge of the pole vector with respect to the reference sphere. THE CONVENTION OPTION DOES NOT AFFECT THE PLOTTING OF DATA, OR THE VALUES IN THE GRID IN ANY WAY!! Legend Note that the Legend for the Pole Plot (and all stereonet plots in DIPS) indicates the:

These can be changed using Stereonet Options in the Setup menu (Equal Area and Upper Hemisphere options can be used). However, for this tutorial, we will use the default projection options. Note that the Legend also indicates "61 Poles, 40 Entries". " The EXAMPLE.DIP file has 40 rows, hence "40 entries". " The Quantity Column in this file allows the user to record multiple identical data units in a single row of the file. Hence the 40 data entries actually represent 61 features, hence "61 poles". Let's move on to the Scatter Plot.U a U U U a U 6...E 4 GEO.DCPP.01.22 Rev. 1 a3 While the Pole Plot illustrates orientation data, single pole symbols may actually represent several unit measurements of similar orientation. Select the Scatter Plot option in the View toolbar or the View menu, to generate a Scatter Plot. Select: View -- Scatter Plot A Scatter Plot allows the user to better view the numerical distribution of these measurements, since coincident pole and closely neighbouring pole measurements are grouped together with quantities plotted symbolically. The Scatter Plot Legend indicates the number of poles represented by each symbol. Let's move on to the Contour Plot, which is the main tool for analyzing pole concentrations on a stereonet.

Select: View -- Contour Plot Figure 2-3: Contour Plot of EXAMPLE.DIP data. The Contour Plot clearly shows the data concentrations. It can be seen that there are three data clusters in the EXAMPLE.DIP file, including one that wraps around to the opposite side of the stereonet. Since this file only contains 40 data entries, the data clustering in this case was apparent even on the Pole Plot"However, in larger DIPS files, which may contain hundreds or even thousands of entries, cluster recognition will not necessarily be visible on Pole or Scatter Plots, and Contour Plots are necessary to identify major data concentrations.

- e Page 95 of 168 December 14, 2001 Calculation 52.27.100.732, Rev. 0, Attachment B, Page a of 90 Quick Tour of DIPS Another widely used technique for representing orientations is the Rosette Plot. The conventional rosette plot begins with a horizontal plane (represented by the equatorial (outer) circle of the plot). A radial histogram (with arc segments instead of bars) is overlain on this circle, indicating the density of planes intersecting this horizontal surface. The radial orientation limits (azimuth) of the arc segments correspond to the range of STRIKE of the plane or group of planes being represented by the segment. In other words, the rosette diagram is a radial histogram of strike density or frequency.
To generate a Rosette Plot, select Rosette Plot from the View toolbar or the View menu. Select: View -+ Rosette Plot 7, -7. 4 Although the default Rosette Plot uses a horizontal base plane, an arbitrary base plane at any orientation can be specified in the Rosette Options dialog. For a non horizontal base plane, the Rosette Plot represents the APPARENT STRIKE of the lines of intersection between the base plane and the planes in the DIPS file.Figure 2-5: Rosette Plot of EXAMPLE.DIP data.GEO.DCPP.01.22 Rev.

In cases where the planes being considered form essentially -two dimensional geometry (prismatic wedges, for example) the third dimension may often overcomplicate the problem. A horizontal rosette diagram may, for example, assist in blast hole design for a vertical bench where vertical joint sets impact on fragmentation. A I vertical rosette oriented perpendicular to the axis of a long topsill or tunnel may simplify wedge support design I where the structure parallels the excavation. A vertical rosette which cuts a section through a slope under -I investigation can be used to perform quick sliding or L M , toppling analysis where the structure strikes parallel to the slope face. From a visualisation point of view and for conveying (a structural data to individuals unfamiliar with stereographic projection, rosettes may be more ' appropriate when the structural nature of the rock is I simple enough to warrant 2D treatment. Weighted Rosette Plot The Terzaghi Weighting option can be applied to Rosette -,l Plots as well as Contour Plots, to account for sampling bias introduced by data collection along Traverses. "* If the Terzaghi Weighting is NOT applied, the scale of the Rosette Plot corresponds to the actual "number of . planes" in each bin. "* If the Terzaghi Weighting IS applied, the scale of the Rosette Plot corresponds to the WEIGHTED number of planes in each bin. Do not use weighted plots for applications unless you are familiar with the limitations. See the DIPS Help system for more information. GEO.DCPP.01.22 Rev.

The Add Set Window option allows the user to draw windows around data clusters on a stereonet, and obtain mean orientations of data (poles) within the windows.Before we go further, note the following: "* The windows created with Add Set Window are curvilinear four-sided windows, defined by two trend values and two plunge values at opposite corners. "* The windows are always formed in a CLOCKWISE direction, therefore you must always START a Set Window with one of the COUNTER-CLOCKWISE corners. Let's create our first Set with the small data cluster at the right side of the stereonet. Select: Sets --> Add Set Window 1. Locate the cursor at APPROXIMATELY Trend/Plunge = 55 / 65, and click the LEFT mouse button. Remember that the cursor coordinates are displayed in the Status Bar. 2. Move the mouse in a CLOCKWISE direction, and you will see a curvilinear, four-sided Set Window opening up. 3. Move the cursor to APPROXIMATELY Trend/Plunge = 115 / 20, and click the LEFT mouse button. You will then see the Add Set Window dialog.GEO.DCPP.01.22 Rev. 1.I.4-i 'F I I U I a U U B U U.U U a A 7i.f?December 14, 2001 Page 100 of 168 Calculation 52.27.1.00.732, Rev. 0, Attachment B, Page_. of 90 18 DIPS Users Guide[Add et Widow E CK Cncel Figure 2-8: Add Set Window dialog.4.

" The mean pole / plane will be displayed according to the visibility settings chosen in the Add Set Window dialog. In this case, we have displayed the Unweighted mean pole vector and plane. "* Unweighted mean poles / planes are identified by an "im" beside the Set ID. Weighted mean poles / planes, if displayed, are identified by a "w" beside the Set ID. Status Bar Display After a Set is created, the Status Bar will display the number of poles in the Set. For this example, the Status Bar should now show: 10 poles from 8 entries in Set 1 [ The "8 entries" refers to the number of rows of the grid within the Set. Since we have a Quantity Column in this file, each row can represent multiple data units (poles). In this case, the 8 rows actually represent 10 poles. Set Column When the FIRST Set is created, a Set Column is automatically added to the Grid. The Set Column records the Set ID of data belonging to Sets. Let's verify this. Return to the Grid View (you may select from the list of open views in the Window menu).
- Notice the Set Column, which appears AFTER the Traverse Column.3.GEO.DCPP.01.22 Rev.

These are the poles within the Set Window just created.
Now return to the Contour Plot view, and we will create another Set, this time with a window which wraps around the perimeter of the stereonet. Wrapped Set Windows After you have selected the FIRST corner of a Set Window with the Add Set Window option, you will notice that if the cursor moves beyond the stereonet perimeter, it will "wrap around" and re-appear on the opposite side of the stereonet, with the window still attached. This allows data near the perimeter, on opposite sides of the stereonet, to be selected as one Set, as illustrated in Figure 2-10.WRAPPED SET WINDOW A wrapped Set Window in DIPS automatically calculates the correct mean vector for Sets which cross the equator.Figure 2-10: Wrapped Set Window.GEO.DCPP.01.22 Rev. 1 ,o E: December 14, 2001 Page 103 of 168 Attachment B, Page JJ"'of 90 Quick Tour of DIPS 21 A U 0 --GEO.DCPP.01.22 Rev. 1 This useful feature of DIPS automatically calculates the correct mean vector for Sets with poles plotting on opposite sides of the equator, since A MEAN ORIENTATION CALCULATED FROM THE LOWER HEMISPHERE ALONE WILL BE INCORRECT!! The poles within a wrapped Set window that plot on the opposite side of the stereonet, are incorporated into the vector addition AS NEGATIVE poles (ie. plunge = plunge , trend = trend + 180), so that the mean will be correctly calculated. Let's create a second Set using a wrapped Set Window. Select Sets -+ Add Set Window 1. Locate the cursor at APPROXIMATELY Trend/Plunge = 300 / 20, and click the LEFT mouse button. Remember that the cursor coordinates are displayed in the Status Bar. 2.

As you can see at the top of the Query Data dialog, an Expression consists of Data, Operator and Operand.
- 1. In the Query Data dialog, click in the Data box at the left of the Expression area, and select TYPE from the drop-down list. 2. Click in the Operand box, and select "joint" from the drop-down list. a 3. The Expression area should now display TYPE -, : 7i%, joint. To create the query, use the buttons at the left of the a *Create Query area to enter the desired expression(s) in the area to the right of the buttons.

"* All entries in the SURFACE column "include" the string "rough"- "sl.rough", "rough" and "v.rough'. This example also demonstrates the use of the "Includes" operator, which finds all entries "including" the substring entered as Operand in the Expression. The New File The new file created after a query is also a DIPS file, with all of the same Job Control and Traverse information as the original file. You can immediately start working with this file. For example: Select: View -+ Pole Plot to generate a Pole Plot of the new subset. Any DIPS option can now be carried out on the new file, including another query. If you want to preserve the new file, it is recommended that you save the file with an appropriate name, before proceeding with further analysis. What About the Set Column? Earlier in this tutorial, we created Sets with the Add Set Window option. When Sets are created in DIPS, a Set Column is automatically added to the Grid.

The Declination is typically used to correct for magnetic declination, but can be used to adjust to grid north. Note that the declination is ADDED to all azimuth values, therefore a POSITIVE value corrects for WEST declination, and a NEGATIVE value corrects for EAST declination (which is the case in this example). Quantity Column A Quantity Column in a DIPS file allows the user to record single data entries which refer to multiple identical features having the same orientation.

Traverse ID The Traverse ID can be any integer value greater than 0. Each Traverse must have its own unique ID. Traverse Orientation Format The Traverse Orientation Format is very important, because it allows the user to combine mixed orientation formats in the same DIPS file.Page 128 of 168 December 14, 2001 Calculation 52.27.100.732, Rev. 0, Attachment B, Page '- of 90 46 DIPS Users Guide Whenever the Traverse Orientation Format is different from the Global Orientation Format, DIPS will interpret the orientation data for the Traverse according to the Traverse Orientation Format. In this example: " l Traverses I and 2 have the same data format as the Global Orientation Format (STRIKEIDIPR). S12 "* Traverse 3 is a BOREHOLE traverse. The Traverse Orientation Format is not applicable, since data is measured in terms of alpha and beta angles on the oriented core. See the DIPS Help system for detailed Ip discussion of BOREHOLE traverses. " Traverse 4 uses a different orientation format from the Global Orientation Format. In this case, the data on Traverse 4 is in DIP/DIPDIRECTION format. Traverse Type Four Traverse Types are available in DIPS:
- LINEAR
- PLANAR
- BOREHOLE
- CLINORULE Traverse Orientation The orientations required to define the Traverse Orientation depend on the Traverse Type, and may also L depend on the Traverse Orientation Format.
- Traverse 1 is a LINEAR traverse.
For a LINEAR traverse, the Orient 1 and Orient 2 values are always in TREND/PLUNGE format.December 14,2001 GEO.DCPP.01.22 Rev. I Page 129 of 168 Calculation 52.27.100.732, Rev. 0, Attachment B, PageS 3 l'of 90 Creating a DIPS File 47 .Traverse 2 is a PLANAR traverse. For a PLANAR "traverse, the Orient 1 and Orient 2 values correspond .to the Traverse Orientation Format, in this case STRIKE/DIPR. Traverse 3 is a BOREHOLE traverse, which requires ': THREE orientations to define. See the DIPS Help system for details. ..Traverse 4 is a PLANAR traverse. In this case, the Traverse Orientation Format is DIP/DIPDIRECTION, therefore the Orient 1 and Orient 2 values are in "DIP/DIPDIRECTION format. Traverse Comment An optional Traverse Comment can be added for each Traverse, to further identify / describe each traverse. ~ :m You may inspect the original EXAMPLE.DIP file to view the comments added for these four traverses. Traverse Column When you are finished entering the Traverse Information, select OK, and you will see that a Traverse Column has been added to the spreadsheet, after the Quantity Column. To The Traverse Column is for recording the Traverse ID of each data unit. In this case, 1, 2, 3 and 4. V -Also notice that the titles of the two Orientation Columns -now Orient 1 and Orient 2, instead of StrikeR and Dip. Since there are mixed orientation formats in this data file (remember that the Traverse Orientation Format for Traverse 4 is DIP/DIPDIRECTION while the Global -.Orientation Format is STRIKE/DIPR), the titles of the Orientation Columns are simply Orient 1 and Orient 2, to avoid misinterpretation of the data.

Extra Columns In DIPS, any columns AFTER the two mandatory Orientation Columns, and the optional Quantity and Traverse Columns (if present), are referred to as Extra Columns. Extra Columns can be used to store any other QUANTITATIVE or QUALITATIVE data that the user wishes to record. Recall that the EXAMPLE.DIP file used three Extra Columns:

Notice that the Shears in this example are not represented in the contours. This is because the number of mapped shears is small. However, due to the low friction angle and inherent persistence, the shear features may have a dominating influence on stability.

Calculation of Q Values RQD, as calculated in the spreadsheet was 60%. Using the JN value of 9, and the upper and lower limits for JR and JA (see above), gives: "* AlowerQof(60/9)*(1/4)*(1/1) =1.7 "* AnupperQof(60/9)*(1.5/3)*(1/1)=3.3 This range of values can now be used for further empirical support design according to Barton's design charts -see Figure 5-6. Real values for JW may be evaluated qualitatively from borehole inflow notes. SRF can be determined from the depth of the proposed excavation according to Barton.Page 168 of 168 December 14, 2001}}
