VARIATION IN UNDRAINED SHEARING STRENGTH BY SEMICONFINED TESTS

THE UNDRAINED SHEARING STRENGTH OF WELLAND CLAY IS DETERMINED OVER A 150 DEGREE RANGE OF SAMPLE ORIENTATION BY THE USE OF SEMICONFINED COMPRESSION TESTS THAT LIMIT FAILURE TO ONE DIRECTION, BUT ALLOW FAILURE ON ANY PLANE IN THAT DIRECTION. IT IS SHOWN THAT THE UNDRAINED SHEARING STRENGTH IS VERY NEARLY SYMMETRICAL ABOUT 1 = 90 DEGREES. THE BJERRUM-KENNEY HYPOTHESIS OF GREATEST SHEAR STRESS RESISTANCE IN THE DIRECTION OF GREATEST SHEAR STRESS DURING CONSOLIDATION IS SLIGHTLY OUT OF PHASE FOR WELLAND CLAY. FOR THE SOIL TESTED, SEMICONFINED TESTS YIELD UNDRAINED SHEARING STRENGTHS ABOUT 20% GREATER THAN UNCONFINED COMPRESSION TESTS. /RATAOC/
