SHEAR STRENGTH OF A KAOLIN

A SERIES OF TESTS WAS CARRIED OUT ON A KAOLIN TO INVESTIGATE THE INFLUENCE OF ANISOTROPIC CONSOLIDATION AND PARTICLE ORIENTATION ON SHEAR STRENGTH BEHAVIOR. SAMPLES PREPARED BY OEDOMETER CONSOLIDATION WERE COMPARED WITH THOSE PREPARED BY NORMAL METHODS AND SUBJECT ONLY TO TRIAXIAL CONSOLIDATION. SHEAR STRENGTH PROPERTIES WERE MEASURED IN A STABILITY ANALYSES BY MEANS OF REASONABLY SIMPLE TECHNIQUES. EXTENSION TESTS. THE RESULTS OF THOSE TESTS VERIFIED, IN GENERAL, CONCLUSIONS DRAWN BY PREVIOUS WORKERS USING REMOULDED SATURATED CLAYS, THAT IS, THAT THE BEHAVIOR IS INFLUENCED GREATLY BY THE OVER-CONSOLIDATION RATIO AND THAT HVORSLEY'S EXPRESSION IS CORRECT. THE RESULTS ALSO INDICATED THAT PARTICLE ORIENTATION HAD LITTLE EFFECT ON THE STRENGTH BEHAVIOR. SMALL DISCREPANCIES FROM THE "IDEAL" BEHAVIOR WERE EXPLAINED USING A MODEL OF CLAY STRUCTURE MADE UP OF GROUPS OF ORIENTED PARTICLES (DOMAINS), THE DIMENSIONS OF WHICH INCREASED WITH THE MAGNITUDE OF THE PRECONSOLIDATION PRESSURE. /RRL/A/
