CHANGES IN SOIL SUCTION IN A SAND-CLAY SUBJECTED TO REPEATED TRIAXIAL LOADING

A LABORATORY INVESTIGATION THAT EXAMINED WHETHER SOIL SUCTION VALUES WERE DEPENDENT ON THE STRESS HISTORY EXPERIENCED BY A SOIL IS REPORTED ON. SPECIFICALLY, THE EFFECTS OF REPEATED TRIAXIAL COMPRESSIVE LOADING ON THE SOIL SUCTIONS OF A KAOLINITE-SAND MIXTURE WERE STUDIED. THE VARIABLES EXAMINED INCLUDED THE EFFECTS OF THE INITIAL AND FINAL DRY DENSITIES AND DEGREES OF SATURATION AND THE MAGNITUDES AND NUMBERS OF THE REPETITIVELY APPLIED STRESSES. BOTH THE MATRIX SUCTIONS AND THE SUCTION-MOISTURE CONTENT RELATIONS WERE STUDIED. IT WAS FOUND THAT THE SUCTION VALUES DEPENDED PRIMARILY ON THE DEGREES OF SATURATION BUT WERE ALSO SLIGHTLY INFLUENCED BY THE DRY DENSITY AND SATURATION; THE REDUCTION WAS THE GREATEST AT THE HIGHEST SATURATIONS STUDIED. AN INCREASE IN THE NUMBER OF LOAD APPLICATIONS ALSO TENDED TO REDUCE THE MATRIX SUCTIONS. THE WORK DEMONSTRATES THE NEED TO CONSIDER STRESS HISTORY EFFECTS IN FUTURE INVESTIGATIONS OF SOIL SUCTION. /AUTHOR/
