THE TESTS ARE PERFORMED IN ONE OF TIlE FOLLOWING 1AYS: UNCONSOLIDATED-UNDRANED: TIlE CONFINING PRESSURE IS IMPOSED ONOTIIE SAMPLE AT THE START OF TIlE TEST, NO DRAINAGE IS PERMITTED AND TIlE STRESSES W`HICH ARE MEASURED REPRESENT TIlE SUM OF TIlE INTERGRANULAR STRESSES AND PORE WATER PRESSURES. CONSOLIDATED-UNDRAINED: TIlE SAMPLE IS ALLO% 1ID TO CONSOLII)ATE FULLY UNDER THE APPLIED CONFINING PRESSURE PRIOR TO TIlE START OF TilE TEST. THE VOLUME CHANGE IS DETERMINED BHY MEASURING TIE WATER AND,'OR AIR EXPELLED DURING CONSOI.IDATIGN. NO DRAINAGE IS PERMITTED DURING THE TEST AND THE STRESSES WIIHCII ARE MEASUREI) ARE TIlE SAME AS FOR THE UNCONSOI.IDATED-UNDRAINED TEST.DRAINED: TIlE INTERGRANULAR STRESSES IN A SAMPLE MAY BE MEASURED BY PER-FORMING A DRAINED, OR SLOA, TEST. IN THIS TEST THE SAMPLE IS FULLY SATURATED AND CONSOLIDATED PRIOR TO THE START OF THE TEST. DURING THE TEST, DRAINAGE IS PERMITTED AND TIlE TEST IS PERFORMED AT A SLOW ENOUGH RATE TO PREVENT THE BUILDUP OF PORE WATER PRESSURIS. THE RESULTING STRESSES WHICH ARE MEAS-URE!) REPRESENT ONLY TIlE INTERGRANULAR STRESSES. TIIESE TESTS ARE USUALLY PERFORMED ON SAMPLES OF GENERALLY NON-COHESIVE SOILS, ALTHOUGH THE TEST PROCEDURE IS APPLICABLE TO COHESIVE SOILS IF A SUFFICIENTLY SLOW TEST RATE IS USED.AN ALTERNATE MEANS OF OBTAINING TIlE DATA RESULTING FROM TIlE DRAINED TEST IS TO PER-FORM AN UNDRAINED TEST IN WHICH SPECIAL EQUIPMENT IS USED TO MEASURE THE PORE WATER PRESSURES. THE DIFFERENCES BETWELEN TIlE TOTAL STRESSES AND THE PORE WATER PRESSURES M EASURED ARE THE INTERGRANULAR STRESSES. ............. ... ........ .........BRAIDWOOD STATION UPDATED FINAL SAFETY ANALYSIS REPORT FIGURE 2.5-56 STRENGTH TESTS, METHODS (SHEET 1 OF 2) METHOD OF PERFORMING DIRECT SHEAR AND FRICTION TESTS DIRECT SHEAR TESTS ARE PERFORMED TO DETERMINE THE SHEARING STRENGTHS OF SOILS. FRICTION TESTS ARE PERFORMED TO DETERMINE THE FRICTIONAL RE-SISTANCES BETWEEN SOILS AND VARIOUS OTHER MATE-RIALS SUCH.AS WOOD, STEEL, OR CONCRETE. THE TESTS ARE PERFORMED IN THE LABORATORY TO SIMULATE ANTICIPATED FIELD CONDITIONS. EACH SAMPLE IS TESTED WITHIN THREE BRASS RINGS, DIRECT SHEAR TESTINiG TWO AND ONE-HALF INCHES IN DIAMETER AND ONE INCH DIRECT S PPARATUS& RECORDING6 APPARATUS IN LENGTH. UNDISTURBED SAMPLES OF IN-PLACE SOILS ARE TESTED I1. RINGS TAKEN FROM THE SAMPLING DEVICE IN WHICH THE SAMPLES WERE OBTAINED. LOOSE SAMPLES OF SOILS TO BE USED IN CON-STRUCTING EARTH FILLS ARE COMPACTED IN RINGS TO PREDETERMINED CONDITIONS AND TESTED.DIRECT SHEAR TESTS A THREE-INCH LENGTH OF THE SAMPLE IS TESTED IN DIRECT DOUBLE SHEAR. A CONSTANT PRES-SURE, APPROPRIATE TO THE CONDITIONS OF THE PIOBLEM FOR WHICH THE TEST IS BEING PER-FORMED, IS APPLIED NORMAL TO THE ENDS OF THE SAMPLE THROUGH POROUS STONES. A SHEARING FAILURE OF THE SAMPLE IS CAUSED BY MOVING THE CENTER RING IN A DIRECTION PERPENDICULAR TO THE AXIS OF THE SAMPLE. TRANSVERSE MOVEMENT OF THE OUTER RINGS IS PREVENTED. THE SHEARING FAILURE MAY BE ACCOMPLISHED BY APPLYING TO THE CENTER RING EITHER A CONSTANT RATE OF LOAD, A CONSTANT RATE OF DEFLECTION, OR INCREMENTS OF LOAD OR DE-FLECTION. IN EACH CASE, THE SHEARING LOAD AND THE DEFLECTIONS IN BOTH THE AXIAL AND TRANSVERSE DIRECTIONS ARE RECORDED AND PLOTTED. THE SHEARING STRENGTH OF THE SOIL IS DETERMINED FROM THE RESULTING LOAD-DEFLECTION CURVES.FRICTION TESTS IN ORDER TO DETERMINE THE FRICTIONAL RESISTANCE BETWEEN SOIL AND THE SURFACESOF VARIOUS MATERIALS, THE CENTER RING OF SOIL IN THE DIRECT SHEAR TEST IS REPLACED BY A DISK OF THE MATERIAL TO BE TESTED. THE TEST IS THEN PERFORMED IN THE SAME MANNER AS THE DIRECT SHEAR TEST BY FORCING THE DISK OF MATERIAL FROM THE SOIL SURFACES.BRAIDWOOD STATION BRAIDWOOD STATION UPDATED FINAL SAFETY ANALYSIS REPORT FIGURE 2.5-56 STRENGTH TESTS, METHODS (SHEET 2 OF 2) Ii.0, 0."I I.I'.0 S.t'J b.b.'Ga k tj 4.GD'hi I..U'Gd'4.'4.hi 4..hi 4.4~hi 4..U hi'4.'4.hi 4 4 g g 186,000--301OO0i 15,000_8.000 t J 0 X AI toSTRAIN (W XIL i -o ,ooo L : I " M S 1O 0 lB o eo AXIAL.

THE COM-PACTION CURVE SHOWING THE RE-LATIONSHIP BETWEEN DENSITY AND MOISTURE CONTENT FOR A SPECIFIC COMPACTING EFFORT IS DETER-MINED BY EXPERIMENTAL METHODS.TWO COMMONLY USED METHODS ARE DESCRIBED IN THE FOLLOWING PARAGRA PHS.FOR THE -STANDARD A.A.S.H.O."

SEVERAL VARIATIONS OF THESE COMPACTION TESTING METHODS ARE OFTEN USED AND THESE ARE DESCRIBED IN A.A.S.H.O. & A.S.T.M. SPECIFICATIONS. FOR BOTH METHODS, THE WET DENSITY OF THE COMPACTED SAMPLE IS DETERMINED BY WEIGHING THE KNOWN VOLUME OF SOIL; THE MOISTURE CONTENT, BY MEASURING THE LOSS OF W'EIGHT OF A PORTION OF THE SAMPLE WHEN OVEN DRIED; AND THE DRY DENSITY, BY COMPUTING IT FROM THE WET DENSITY AND MOISTURE CONTENT. A SERIES OF SUCH COMPACTIONS IS PERFORMED AT IN-CREASING MOISTURE CONTENTS UNTIL A SUFFICIENT NUMBER OF POINTS DEFINING THE MOISTURE-DENSITY RELATIONSHIP HAVE BEEN OBTAINED TO PERMIT THE PLOTTING OF THE COMPACTION CURVE.

UTILIZING THE RESONANT COLUMN APPARATUS, A CYLINDRICAL COLUMN OF SOIL OR ROCK IS SUBJECTED TO A STEADY STATE SINUSOIDAL FORCING FUNCTION, WHICH.STRESSES THE SAMPLE IN TORSION. THE FREQUENCY OF THE APPLIED FORCE IS VARIED UNTIL THE RESONANT FREQUENC) OF THY SOIL APPARATUS SYSTEM IS OBTAINED. THE RESONANT FREQUENCY IS THAT WHICH PRODUCES THE MAXIM,].UM AMPLITUDE OF OUTPUT RECORDED. THE RESONANT FREQUENCY THUS OBTAINED IS RELATED TO THE TORSIONAL SHEAR MODULUS OF THE MATERIAL TESTED.RESONANT COLUMN TESTS ARE PERFORMED ON UNDISTURBED OR RECONSTITUTED CYLINDRICAL SAMPLES OF SOIL APPROXIMLATELY 6 INCHES IN LENGTH AND 2q INCHES IN DIAMETER. THE SAMPLES ARE ENCASED IN A RUBBER MEMBRANE AND PLACED IN A TEST CHAMBER. THE TESTS MAY BE PER-FORMED CONFINED OR UNCONFINED ON SOILS AT FIELD MOISTURE OR ON ARTIFICIALLY SATURATED SAMPLES. THE APPARATUS EMPLOYS A VIBRATION EXCITATION DEVICE, POWERED BY A VARIABLE FREQUENCY SINE WAVE GENERATOR AIWCH APPLIES A FORCING TORQUE TO THE FREE END OF THE SPECIMEN. THE RESULTING VIBRATIONS ARE MEASURED BY AN ACCELEROMETER WHICH PRODUCES A CALIBRATED OUTPUT THAT IS A MEASURE OF THE ANGULAR ACCELERATION OF THE FREE END OF THE SPECIMEN. THE SINUSOIDAL VOLTAGE USED TO PRODUCE THE FORCING TORQUE AND THE OUTPUT OF THE ACCELEROMETER ARE DISPLAYED OiN THE X-V AXES OF THE OSCILLOSCOPE RE-SULTING IN ELLIPTICAL CONFIGURATIONS FOR ASSOCIATED FREQUENCIES. THESE ELLIPTICAL LOOPS ARE PHOTOGRAPHED AND EVALUATED TO DETERMINE THE DAMPING CHARACTERISTICS OF THE SAMPI.FS TESTED.
