Constitutive Model of Saturated Structural Clays Based on SMP Failure Criterion

Abstract:

For normal consolidated or low over consolidated saturated structured clays, a constitutive model of the clay was proposed by introducing a structural parameter d in order to quantitatively describe the change of its deformation and strength based on unified hardening model. Stress-strain and body strain of the clay were predicted by the new model and were measured by K0 consolidated compression and shearing tests. The rationality and feasibility of the new model were proved by comparing the predictive and experimental value. The results show that the model can well describe structural characteristics, deformation and mechanical properties of the saturated structured clays; predictive value of stresses and strains are basically in agreement with experimental ones, and this further proves the rationality and feasibility of the new model.
