Abstract

Abstract

Under the condition of undiminished cyclic loading,the plastic deformation of soil can not be described by using classical elastoplastic models in the reloading process. The UH model can be used to describe many characteristics of clay well, including stress dilatancy, strain hardening and softening, and path dependency behaviour. It can also be used to describe the plastic deformation in the reloading process under the condition of cyclic loading. The UH model was applied under complex stress path condition. The numerical simulation of the bearing capacity of foundation was performed. The p-s curves of the foundation calculated by using the UH model and Camclay model were analyzed. The stress-strain characteristics of nodes at different positions on the surface were analyzed. Based on the results,it was found that the UH model could rationally exhibit the soil behaviors under the complex loading condition.
