EFFECTS OF REPEATED LOADING ON THE STRENGTH AND DEFORMATION OF COMPACTED CLAY

Abstract

THIS PAPER PRESENTS RESULTS OF TESTS MADE TO DETERMINE SOME EFFECTS OF REPEATED LOADING ON THE STRENGTH AND DEFORMATION OF COMPACTED SPECIMENS OF A SILTY CLAY IN TRIAXIAL COMPRESSION TESTS. APPARATUS FOR APPLYING REPEATED LOADS OF VARYING PERIODS AND FREQUENCIES TO TEST SPECIMENS IS DESCRIBED. TEST DATA TO COMPARE THE EFFECTS OF REPEATED LOADS AND SUSTAINED LOADS ON THE STRENGTH AND DEFORMATION OF TEST SPECIMENS AND THE EFFECT OF FREQUENCY OF LOADING AND MAGNITUDE OF APPLIED STRESS ON THE DEFORMATION OF PARTIALLY SATURATED SPECIMENS SUBJECTED TO 50,000 TO 100,000 APPLICATIONS OF STRESS IS PRESENTED. IN ADDITION, DATA ON THE COMPRESSION AND REBOUND OCCURRING DURING REPEATED LOAD APPLICATIONS ARE ANALYZED. CONCLUSIONS ARE DRAWN WITH REGARD TO THE EFFECTS OF FREQUENCY OF LOADING AND MAGNITUDE OF LOADING ON THE DEFORMATION OCCURRING DURING REPEATED STRESS APPLICATION. /AUTHOR/
