TIME-DEPENDENT DEFORMATION CHARACTERISTICS OF COMPACTED COHESIVE SOILS

EXPERIMENTAL INVESTIGATIONS OF TIME-DEPENDENT SHEAR STRAIN CHARACTERISTICS OF COMPACTED COHESIVE SOILS UNDER A STEP DEVIATOR STRESS LOAD WERE CONDUCTED. IT WAS FOUND THAT BY EXPRESSING CREEP PARAMETERS AS A FUNCTION OF THE RATIO OF THE DEVIATOR STRESS TO THE DEVIATOR STRESS AT FAILURE THE EFFECTS OF CONFINING PRESSURE AND MOISTURE CONTENT COULD BE ACCOUNTED FOR. IT IS SHOWN THAT THE RESPONSE UNDER SECOND CYCLE OF LOADING IS MORE IMPORTANT FOR FIELD STRUCTURES AND THAT THE MATERIAL CONSTANTS OBTAINED FOR SMALL SAMPLES IN THE LABORATORY ARE VALID FOR LARGE STRUCTURES ALSO. WHEN THE PRINCIPAL STRESS DIRECTIONS WERE CHANGED, THE CHANGE IN STRESS-STRAIN-TIME BEHAVIOR OF THE COMPACTED SOILS INDICATE THAT THEY BEHAVED AS ANISOTROPIC MATERIALS. IT WAS FOUND THAT NONLINEAR VISCOELASTIC CONSTITUTIVE EQUATIONS MAY BE USED TO PREDICT THE CREEP AND RECOVERY BEHAVIOR OF THE COMPACTED CLAYS TESTED. /AUTHOR/
