THE EFFECT OF OVERCONSOLIDATION ON THE UNDRAINED STRENGTH OF CLAYS

IN ORDER TO EXAMINE THE POSSIBILITY OF APPLYING THE ANGLE OF SHEARING RESISTANCE IN TERMS OF TOTAL STRESS = O ANALYSIS TO THE LONG-TERM STABILITY PROBLEM, EXPERIMENTAL STUDIES ON THE STRENGTH OF OVERCONSOLIDATED CLAYS WERE PERFORMED. TRIAXIAL COMPRESSION TESTS WERE CONDUCTED ON FOUR SATURATED MARINE CLAYS, IN WHICH THE SPECIMEN WAS ALLOWED TO REBOUND UNDER AN ISOTROPIC OR ANISOTROPIC CONFINING PRESSURE BEFORE SHEAR. IN SPITE OF A CONSIDERABLE DIFFERENCE IN INDEX PROPERTIES, THREE UNDISTRUBED CLAYS SHOWED SIMILAR PATTERNS OF STRENGTH REDUCTION DUE TO THE ISOTROPIC REBOUND. THE STRESS ANISOTROPY WAS FOUND TO HAVE SOME INFLUENCE ON THE STRENGTH REDUCTION DUE TO REBOUND. IT WAS ALSO SHOWN THAT THE SECANT MODULUS OF STRESS-STRAIN CURVE DECREASES WITH THE OVERCONSOLIDATION RATIO. /RRL(A)/
