r TESTIMONY OF DR. ALFRED J. HENDRON, JR.

This is, the testimony of Dr. Alfred J. Hendron, Jr. My testimony is concerned with the evaluation of the seismic shakedown settlement of the Diesel Generator Building at the Midland nuclear power plant in the event of an earthquake. The seismic shakedown settlement of the DGB was evaluated for an intensity of motica which would correspond to an upper bound ground surface acceleration 0.199 . I have concluded that the north side of the DGB will settle about .25" 1 15" under an earthquake acceleration of 0.19g and the scuth side will settle about .05" 1 05". The North side of the building will settle more during the earthquake because there is a larger thickness of sand under the north side nf the DGB. The building will tend to rotate slightly toward the north during seismic shaking just as it has tended to rotate south during static settlement due to the higher percentage of clay under the south side of the building.

QUALIFICATIONS AND EXPERIENCE My detailed biographical, educational, and professional record is set-forth in Attachment I. The following is a sumary.

I. completed the requirements for the degree of Bachelor of Science in ,

Civil Engineering from the University of Illinois in June of 1959. In September of 1959 I enrolleo in the Graduate College of the University of Illinois where I began full-time study on a University of Illinois Fellowship in the Department of Civil Engineering, specializing in Soil Mechanics and Foundation Engineering. I received the degree of Master of Science in Civil

Engineering from the University of Illinois in June of 1960.. During the sunrner. of- 1960 I wa's employed by'the consulting engineering firm of Shannon -

a-. and ' Wilson,rInc. of _ Seattle, where I worked on foundations' forIthe building complex which housed the World Fair.in Seattle, and conducted .an analysis of-theistability of- a 200 acre slope. adjacent to' the Pacific Ocean to be used' in expert testimony- of Mr. S. D. . Wilson and Dr.' A. Casagrande.--

In the fall of 1960, I-began full-time study:at the University of

. Illinois toward a Ph.D. in Foundation-Engineering and full minors in Geology-and in Theoretical and Applied Mechanics. During this phase of my education, my academic adviser was Dr. Don U. Deere, under whom I studied engineering geology. . I studied. foundation engineering under Dr. R. B. Peck. My studies on the application of shear strength of cohesive soils to problems of slope stabs iity and bearing capacity, problems usually analyzed by limit equilibrium methods, were in courses taught by Dr. R. B. Peck, Dr. Alan Bishop, and Dr. D. U.'Deere.

In June of 1961, I became a full-time research associate at' the

. University of. Illinois where I , conducted a research project'in soil dynamics under Professor N. M. Newmark and I taught an undergraduate course in Soil Mechanics and-Foundation Engineering under Dr. R. B. Peck. These duties con-tinued until the completion of my Ph.D. thesis in the suniner of 1963, when I became a 1st Lieutenant in the U. S. Army Corps of Eng heers.

u

'From September 1963 to September 1965 I was assigned to the U. S. Army Engineer _ Waterways Experiment Station as a research engineer. At-the Waterways Experiment Station I worked in research in soil dynamics and struc-tural dynamics as applied to problems in the design of protective structures.

I was also. instrumental in starting a rock mechanics research program at the

.c w

3

. Waterways Experiment Station, and I' served as a special consultant for the s . Office of the Chief of Engineers on construction _ problems associated with the Minute Man System in North Dakota and as a consultant to NATO in Norway on the construction o'f'a large underground cavity in rock.

Since September of 1965 I have been employed in teaching and research at the University of Illinois in the Department of Civil Engineering, as an Assistant Professor from 1965 to 1968, an Associate Professor from 1968 to 1970, and as a Professor of Civil Engineering from 1970 until present. During this time I have taught graduate courses in soil and rock dynamics, applied foundation engineering, earth dams, rock _ mechanics, and rock engineering. I have also taught undergraduate courses in Introductory Soil Mechanics and Foundation Engineering. I have been active in research on slope stability in rock masses, design of tunnel linings. in soil and rock, ground vibrations pro-duced by construction blasting and by nuclear explosions, theoretical studies of inelastic and time-dependent stress distribution around tunnels in soil and rock, and compressibility of larg,c sized granular materials such as rock fill materials.

While a staff member at the University of Illinois, I have been engaged

, by various public agencies, consulting engineering firms, utility companies, and foreign governments to consult on the design and construction of nuclear power plants, dams, tunnels, and slope stability problems. A number of these consulting assignments are listed in detail in Attachment I.

I have previous experience in the evaluation of foundations of dams and nuclear power plants for liquefaction potential. In those cases where liquefaction has been eliminated by means of dewatering, I have estimated

l g

4 seismic shakedown by the methods used in this testimony.

'N .

_ Diesel Generator Building Description and Available Information Useful for Estimating Seismic Shakedown Settlement The Diesel Generator Building for the Midland Nuclear Station is located to the south of the Turbine Building as shown in Figure 1. The building is founded on a 10 ft wide continuous wall' footing around the peri-meter of the structure; in addition three' North-South wall footings,_also 10 ft wide, support the walls which separate the four bays of the Diesel Generator Building. A plan view of the footings is shown-in Figure 2. The strip footings analyzed and reported in-this testimony are shown by the dark shaded areas in Figure 2. A cross-section taken from west to east through the Diesel Generator Building is shown in Figure 3. The base of the footings are founded at elevation 628 and the finished grade elevation is 634. The static water levels in the area of the diesel generator building will be dewatered_to about elevation 600 to eliminai;e ,the pcssibility of liquefaction in the sands below the north side of the DGB. Thus the sands between elevation 600 and the base of the footings at elevation 628 will be partially saturated and will undergo some permanent vertical strain induced by the cyclic shear strains produced by the earthquake ground motions. The magnitude of the DGB settle-ment which results from the vertical " shakedown" strains is a function of the thickness of sand layers present between elevation 600 and 628, the relative density of the sands, and the n'agnitude of the cyclic shear strains produced by the earthquake.

e 5

The thickness and_ relative density of the sands present beneath the'.

s .

diesel generator' footings must_be obtained from soil boring information. The magnitude of the cyclic strains induced by the SSE can be calculated as illustrated later in this testimony.

Before surcharging in- January of 1979, an exploratory program was con-ducted in the plant area by Bechtel from August 1978 to December 1978 which included borings-in the series designated as DG borings. Borings were also made in 1979 after the surcharge removal and they are designated CH borings.

The location of the borings is shown in Fig. 4. _In some of the DG and CH borings standard penetration tests were obtained at intervals ranging from l.5' to 3.5'. _Those borings with complete enough information to estimate the thickness and relative density of the sand were used to estimate shakedown settlement, in these borings, listed in Table 1, samples were described clo-sely enough to determine if the blow cnunt was taken in sand or clay and the samples were obtained close enough to~ reasonably determine the thickness of clean sand. The boring logs of the borings shown in Table'1 are given in Attachment 2.

Consumers Power has subsequently conducted the additional boring and sampling program requested by the Corps of Engineers. Five of these borings, designated as COE 8, 10, 11, 12 and 13 were made in the area of DGB as shown in Fig. 4. These borings, which were continuously sampled except for boring COE-12, enabled an exact determination of the thickness of sand and clay at each boring location. In those instances where sand was encountered, the relative density of the sand was determined by Woodward-Clyde Consultants by several methods. The COE borings were taken after surcharging; the logs of COE borings 8, 10, 11, and 13 are shown in Attachment 3.

s 6-DESCRIPTION OF THE METHOD FOR CALCULATION OF " SHAKEDOWN" SETTLEMENT s .

The first step-in the calculation of' the " shakedown" settlement is to

1) obtain.the thickness of each sand layer from the boring logs ar.d to obtain the relative density for each sand layer. For the COE borings the relative i

density can be obtained from the Woodward-Clyde Consultants report'of July 1981. For the DG and CH borings the relative density is. determined from the  !

Gibbs & Holtz relationship shown in Fig. 5 by using the standard penetration resistance for each layer and the " effective" stess at the location of the standard penetration test at the time of the boring.

The second step is to 2) determine the total vertical stress at the middle of each layer, o y, which consists of the soil overburden pressure and the distributed vertical stress from the load of the building.

The third step is to 3) determine the average cyclic shear stress which will be applied to the center of each sand layer by T = (0.65) a max o y 9 where T is th'e'iverage shear stress a max. is the maximum acceleration associated with the earthquake, g is the acceleration of gravity, and "v is the total vertical stress at the center of the sand layer (Seed and Idriss 1971).

In the relationship above, the value of 0.65 is the commonly accepted value for reducing the peak shear stress to the average cyclic shear stress for the duration of shaking.

E 7

The fourth step is to 4) determine.the average principal effective 5.- _s' tress at'the center of:the sand-layer, E m, where m = 1/3 (Oy + 2Koo) y and,.Ko,_the lateral earth pressure coefficient is taken as 0.7 for compacted soil.

Th'e fifth step is to 5) calculate the shear modulus, G, using G = 1000 k2 ( m)I where "m is in psf and K2 is in (psf)1 and is a function of relative density and' shear strain, Y, as shown in Fig. 6.

The sixth step is to 6) determine the shear strain by taking Y = T /G.

Since G = f(Y), as shown in Figure 6, the shear strain, Y , is then recalcu-i lated in step 7. Step 6) and 7) must be repeated until the assumed shear strain Y and the computed shear strain are in close agreement. After the cyclic shear strain, Y , has been determined, the vertical " shakedown" strain can be obtained from Fig. 7. Note that the data points shown in Fig. 7 are for 10 cycles of strain which i.s,ponservative for the SSE postulated for the Midland plant; for relative densities different than those which correspond to the curves in Fig. 7, an interpolation is required. The vertical settlement for each boring location is then determined in step 8) by integrating the vertical strain in-all sand layers between elevation 600 and 628. The values of settlement computed in step 8) are then multiplied by 3 in step 9) to account for 3 dimensional shaking as discussed in Pyke, Seed, and Chan (1975).

It is significant that the procedure above, including the multiplication fac-tor of 3, led to agreement between calculated and observed shakedown settle-ment at the Jensen Filtration Plant during the 1971 San Fernando Earthquake (Pyke, Seed & Chen 1975).

s~

8 Calculation of " shakedown";settleinent by the above procedures are given

s. in Attachment 4 for the boring location shown'in Table 1. The calculations given in Att'achment 4 are for a ground surface acceleration of 0.19g and for a magnitude earthquake which would produce 10 significant cycles of average shearst[ess. The results of these calculations are shown in Table 2 and are illustrated on Fig. 8.

RESULTS OF " SHAKEDOWN" SETTLEMENT CALCULATIONS It is felt that the most complete boring information which could be

.used to calculate the shakedown settlement is the:information obtained from the COE boring 8, 10, 11, and 13. These indicate that the north side of the building (Fig. 8) could settle .17" and the south side of the building could settle .05". Then the building would tend to rotate toward the north during shaking just as it has rotated toward the south due to static settlements.

Calculated settlements based on blow counts from the DG and CH borings are also shown on Fig. 8. The calc,ulated settlements for the DG and CH boring locations ranged from .006" to .39". The pattern of settlement indicated by the DG and CH borings also indicate more shakedown rettlement on the north-side of the building. If the calculated settlements at the DG boring loca-tions on the north side of the building are averaged, the average calculated settlement of the north side would be .19". It is my judgment that the settlement of the north side of the building should be considered to be .25" +

.15" and that the south side of the building should settle on the order of

.05" + .05" due to seismic shakedown. The building would tend to rotate as a rigid body about an east-west axis through the center of the building.
