CREEP AND LONG-TERM STRENGTH OF SOILS SUBJECTED TO VARIABLE LOAD

THIS TWO-PART PAPER DEALS WITH PROBLEMS OF CREEP AND LONG-TERM STRENGTH OF CLAYEY SOILS, TAKING INTO ACCOUNT THE VARIATION IN LOAD AND SOIL PROPERTIES IN TIME. THE FIRST PART EXPLAINS THE MECHANISM OF DEFORMATION IN ONE-DIMENSIONAL COMPRESSION AND SHEAR, AND AN INVESTIGATION IS PRESENTED INTO THE VALIDITY OF APPLYING CREEP THEORIES TO SOILS. EXPERIMENTAL AND THEORETICAL RESULTS APPEAR TO COINCIDE. IN THE SECOND PART, THREE LONG-TERM STRENGTH FORMULAE ARE APPLIED TO SOILS AND EXPERIMENTAL AND THEORETICAL DATA COMPARED. FORMULAE ARE SUBSTANTIATED BY PRACTICAL INVESTIGATIONS INTO THE CHANGES IN SOIL STRUCTURE DURING CREEP PROCESSES. A GENERALIZED LONG-TERM STRENGTH EQUATION IS PRESENTED WHICH TAKES INTO ACCOUNT VARIATIONS IN LOAD AND SOIL DENSITY AND TEMPERATURE. /RRL/
