WSES-FSAR-UNIT-32.5A-1APPENDIX 2.5ALABORATORY TESTING2.5AGENERAL SAMPLE HANDLINGAll undisturbed in situ samples were transported horizontally in specially constructed wooden shippingcrates and cushioned against sudden movements. All samples including undisturbed samples, jar samples, and bulk samples were transported from the field by special van to the laboratories of Law Engineering Testing Company in Marietta, Georgia and Eustis Engineering Company of New Orleans, Louisiana. Class A backfill material reconstituted for testing was sent to Woodward Clyde Consultants in Clifton, New Jersey.In the laboratory undisturbed samples were removed from their wooden shipping crates and placedhorizontally in racks for storage. Each sample assigned for laboratory tests was cut into six in. long sections with a band saw and then extruded from its protective tube. During the cutting and extrusion process, the laboratory's project engineer or a designated staff engineer inspected the samples to confirm that they were representative of the appropriate stratum. Various tests were run on selected specimens to determine the engineering parameters of the subsurface materials (i.e. classification, strength, consolidation and dynamic tests). General descriptions of the individual tests and test procedures within the various test categories are included in subsequent subsections.2.5A.1CLASSIFICATION TESTS a)Grain Size Distribution TestsGrain size tests were performed on representative specimens using the wet preparation methodof soil samples as described in ASTM D 2217. Materials consisting primarily of sand and silt were passed through a set of nested sieves as described in ASTM D 422.Soils containing significant amounts of fine-grained material were first passed through nestedsieves and washed on the No. 200 sieve. Hydrometer analyses were performed on particles finer than the No. 200 sieve as described in ASTM D 422. The particles were suspended in distilled water containing five grams per liter (gpl) deflocculent and the grain size distribution computed from the time rate of settlement of the different size particles.b)Atterberg Limits TestsAtterberg limits tests were performed on selected specimens to determine plasticitycharacteristics. The wet preparation method of soil specimen was used for all plasticity tests as described in ASTM D 2217. The liquid limit (LL) was determined by the one point method in accordance with ASTM D 423. The plastic limit (PL) was determined in accordance with ASTM D 424.c)Moisture Content Tests WSES-FSAR-UNIT-32.5A-2Moisture content determinations were made on representative undisturbed tube and cartonsamples and jar samples in accordance with ASTM D 2216. Moisture content and unit weight determinations of undisturbed samples were made on trimmed specimens ready for testing. The trimmed specimen was weighed and measured prior to testing and oven dried to constant weight upon test completion.d)Specific GravitySpecific gravity tests were performed in accordance with ASTM D 854 on selected undisturbedspecimens subjected to consolidation testing.2.5A.2STRENGTH TESTSa)Unconfined Compression TestsUnconfined compression tests were performed on representative Recent and Pleistocenematerial specimens at their natural moisture content. Controlled strain tests were performed as described in ASTM D 2166 on 1.4 in., two in., and four in. diameter specimens. Unconfined compression tests were also performed on test specimens cut horizontally from the sample as well as vertically.b)Triaxial Shear TestsThe strength parameters of the various strata were obtained by triaxial shear tests onrepresentative undisturbed tube samples. Specimen preparation for triaxial shear testing wasperformed as described in ASTM D 2850.Specimens were back-pressure saturated prior to testing by applying a differential pressure of twopsi across the specimen as the chamber pressure and back pressure were increased slowly sothat the specimen could adjust to each pressure increment. The pressure was increased aboutfive psi every 30 minutes or longer.Upon reaching a chamber pressure of 40 psi, the degree of saturation was checked by measuringSkempton's "B" value. If the pore pressure increase was less than the chamber pressureincrease, the sample was again subjected to increasing chamber and back pressures at two psidifferential until saturation was accomplished.Saturated specimens were then consolidated to confining pressures within the range of existingand anticipated stress levels. Consolidation of the sample was measured and the specimen was allowed to drain until 100 percent consolidation was accomplished.1)Unconsolidated Undrained Triaxial TestsUnconsolidated undrained triaxial shear tests were performed on representativeundisturbed specimens of Recent and Pleistocene materials. Testing was done in accordance with ASTM D 2850. The test specimen was encased in a rubber membrane and placed in the load cell. Immediate application of confining pressure and vertical load followed with drainage prohibited.

WSES-FSAR-UNIT-32.5A-32)Consolidated Undrained Triaxial TestsConsolidated undrained triaxial tests were performed on selected specimens of Recentmaterial and Pleistocene clay material. Specimen preparation was performed as described in Subsection 2.5A.2.b. Test specimens were encased in a rubber membrane and placed in the load cell. The specimen was allowed to fully consolidate under the cell confining pressure. With consolidation complete, the specimen was sheared withdrainage prohibited. Tests where pore water pressure measurements were made weresheared at a controlled strain rate allowing the equalization of pore water pressure throughout the specimen.3)Consolidated Drained Triaxial TestsTwo series of isotropically consolidated drained triaxial tests were performed on the ClassA backfill material. One series of tests was loaded along an active stress path where the vertical stress was held constant while the horizontal stress was decreased. The secondseries was loaded along a passive stress path where the vertical stress was held constantwhile the horizontal stress was increased.All consolidated drained tests were performed on reconstituted test specimens. Thespecimens (two in. diameter by four in. height) were compacted in eight layers. To obtain a uniform density, the bottom layer had to be slightly undercompacted since compaction of each succeeding layer densified the sand in the layer below it. This is defined as percent undercompaction, U n . The U value in each layer is linearly varied from thebottom to top layer with the bottom (first) layer having the maximum U n value. The Uvalue selected, in this case, for the first layer was two percent. After the specimens weresaturated by back pressuring and the use of CO 2 at an effective stress of five psi, theywere consolidated in increments to the required effective consolidation stress. This stress was applied one day prior to loading to failure. Loading to failure was done at rates slowenough to assure complete drainage of the test specimen.c)Direct Shear TestsUnconsolidated undrained (quick) direct shear tests were performed on several specimens takenfrom undisturbed Recent and Pleistocene material tube samples. The trimmed specimen was placed in the testing frame and a normal load was applied. These loads were typical of in situ stress conditions encountered in the field. Before allowing the specimen in to consolidate under the normal load it was sheared horizontally producing undrained strength results similar to the unconsolidated undrained triaxial test results.2.5A.3CONSOLIDATION TESTS Consolidation tests were performed on representative undisturbed specimens. The test procedure wasgenerally in accordance with ASTM D 2435. The specimens were first trimmed to approximately 2-1/2 in.

in diameter and one in. in height and placed in a stainless steel ring coated on the inside with a low friction material. The specimen was then weighed in WSES-FSAR-UNIT-32.5A-4the ring, and porous stones were placed at both ends of the ring and fitted with a rubber membrane toprevent moisture loss. Vertical loads were then applied to the specimen and increased incrementally at a load increment ratio of one. The resulting deformation of the soil was measured with a micrometer dial gage. Each load was left on the specimen until completion of 100 percent primary consolidation.Each specimen was rebounded from a stress equal to or slightly greater than the effective overburdenpressure. After rebounding to a load typically one ksf or two ksf the loads were increased in the samemanner as initially applied until an assigned pressure exceeding the anticipated future soil pressure wasreached. The specimen was then incrementally unloaded as during the rebound sequence, back to the original seating load on the specimen.2.5A.4ELASTIC PROPERTIES a)Shear Modulus and DampingLaboratory determinations of elastic soil properties were made by performing load controlledcyclic triaxial tests. Specimens were selected for cyclic triaxial shear tests being representative ofthe soil strata at the site. These specimens were trimmed into cylinders 1.4 in. or two in. in diameter and encased in rubber membranes. Each specimen was then placed in a compression chamber and confined by pressure equivalent to the effective overburden pressure. The specimens were consolidated at this pressure until volume change ceased or 100 percent consolidation had been achieved. After consolidation, the specimens and chamber were placed in an MTS closed loop control system equipped with a Baldwin-Lima Hamilton load cell. This system was equipped to establish load as a direct primary control parameter. In this manner, a cyclic deviator stress was applied to each specimen. With each application of cyclic deviator stress, recordings of load and deformation with respect to time were made. On each specimentested, several ranges of cyclic deviator stress were applied with corresponding recordings of loadand deformation. Hysterisis loops were plotted from the recorded data and shear strain were calculated therefrom. Utilizing this data, the shear modulus was calculated for each application of cyclic deviator stress to each specimen. The shear modulus was calculated for each specimen for varying shear strain levels.b)Poisson's Ratio DeterminationTwo specimens were selected for determination of Poisson's ratio. Each specimen was trimmedto 1.4 in. in diameter, and encased in a rubber membrane. The sample was then placed in atriaxial cell and consolidated under an all-around air pressure equivalent to the effective overburden pressure. The triaxial chamber utilized in this test was equipped with a lateral strain measuring device. This device consisted of three small feeler arms fixed to the base of the cell and bearing against the specimen. These arms were spring-loaded but the spring force wassmall enough so that lateral strain of the specimen was not hindered by their presence. Each arm was equipped with a strain gauge which output lateral movement of the specimen in terms ofstrains in the feeler arms. Small increments of deviator stress were applied with measurements of the resulting axial and lateral strain. Poisson's ratio was calculated for each specimen as the ratio of change in lateral strain to change in axial strain.
