SHEAR STRENGTH OF CLAYS SUBJECTED TO VIBRATORY LOADING

TEST DATA ARE PRESENTED TO SHOW THE SHEAR STRENGTH CHARACTERISTICS OF AN UNDISTURBED WEATHERED CLAY AND A NORMALLY LOADED SOFT CLAY UNDER VIBRATORY LOADING. IT WAS SEEN THAT THE SHEAR STRENGTH DECREASED WITH AN INCREASE IN THE AMOUNT OF ENERGY IMPARTED TO THE SOIL BY THE VIBRATION. THIS WAS A FUNCTION OF THE FREQUENCY, MAXIMUM PARTICLE ACCELERATION, LENGTH OF PERIOD OF VIBRATION PRIOR TO SHEAR, AND MAGNITUDE OF THE VIBRATORY STRESS. THE VIBRATION HAD A GREATER INFLUENCE ON THE STRENGTH OF THE WEATHERED CLAY THAN ON THE SOFT CLAY. THE EFFECTS OF VIBRATION WERE EXPLAINED BY THE FAILURE OF INTERPARTICLE BONDS AND PARTICLE REORIENTATION DURING VIBRATION. THE MAGNITUDE OF THE DECREASE IN STRENGTH WAS DEPENDENT ON BOTH THE VIBRATION ENERGY AND THE INITIAL STABILITY OF THE SOIL STRUCTURE. /AUTHOR/
