SHEAR STRENGTH CHARACTERISTICS OF THE STIFF BANGKOK CLAY

AN INVESTIGATION WAS CARRIED OUT ON UNDISTURBED SAMPLES OF THE STIFF BANGKOK CLAY TAKEN FROM AN AVERAGE DEPTH OF 38 FEET AT THE NEW CAMPUS OF THE ASIAN INSTITUTE OF TECHNOLOGY AT RANGSIT, 40 KILOMETERS NORTH OF BANGKOK. CONVENTIONAL ISOTROPICALLY CONSOLIDATED UNDRAINED TRIAXIAL COMPRESSION TESTS WITH PORE PRESSURE MEASUREMENTS WERE USED IN THE INVESTIGATION. THE SOIL SAMPLES TESTED WERE GROUPED INTO TWO SERIES. IN THE FIRST SERIES, THE SAMPLES WERE CONSOLIDATED AT THE CONFINING PRESSURE TO BE USED IN THE PARTICULAR TEST. IN THE SECOND SERIES, THE SAMPLES WERE FIRST CONSOLIDATED AT A MAXIMUM PAST PRESSURE OF 90 LB PER SQ IN., AND THEN ALLOWED TO SWELL UNDER VARIOUS LOWER CONSOLIDATION PRESSURES PRIOR TO SHEAR. THE TEST RESULTS SHOW THAT THE STIFF BANGKOK CLAY IS AN OVERCONSOLIDATED CLAY WITH A MAXIMUM PAST PRESSURE OF ABOUT 60 LB PER SQ IN. THE OVERCONSOLIDATION HAS BEEN ATTRIBUTED TO DESICCATION. /TRRL/
