EFFECT OF ANISOTROPY ON SOIL STRENGTH PARAMETERS

THE COHESIVE AND FRICTIONAL RESISTANCE OF A CLAY AS RELATED TO THE STRUCTURAL ARRANGEMENT OF THE SOIL PARTICLES WAS EVALUATED BY MEANS OF LABORATORY EXPERIMENTS UTILIZING COHESION-FRICTION-STRAIN TRIAXIAL TESTS. THE EXPERIMENTAL WORK WAS PERFORMED USING PERMIAN RED CLAY SAMPLES WHICH HAD BEEN ISOTROPICALLY AND ANISOTROPICALLY CONSOLIDATED. THE PARTICLES OF AN ANISOTROPICALLY CONSOLIDATED SOIL SAMPLE TENDED TO BE ORIENTED WITH THEIR MAJOR AXES PERPENDICULAR TO THE DIRECTION OF THE MAJOR PRINCIPAL CONSOLIDATION STRESS. TEST SPECIMENS OF THIS SOIL EXHIBITED GREATER COHESION AND SMALLER ANGLES OF INTERNAL FRICTION WHEN LOADED WITH THEIR AXES ORIENTED PERPENDICULAR TO THE DIRECTION IN WHICH THE CONSOLIDATION PRESSURE WAS APPLIED. ISOTROPIC CONSOLIDATION, ON THE OTHER HAND, FAVORED A RANDOM ORIENTATION OF THE SOIL PARTICLES FOR ALL WATER CONTENTS. ONLY NEGLIGIBLE CHANGES IN INITIAL PARTICLE CONFIGURATION OCCURRED, RESULTING, AT MOST, IN MINOR VARIATIONS OF THE COHESIVE AND FRICTIONAL RESISTANCE AS THE ORIENTATION OF THE SPECIMEN AXIS CHANGES. /AUTHOR/
