Abstract

Abstract

Based on the subloading yield surface and the Cam-clay model,the proposed unified hardening model is used to describe the characteristics for over-consolidated clay with structure,including strain hardening,strain softening and stress dilatancy.The constitutive model for over-consolidated clays with structure is proposed introducing the parameter related to the structure of clays and requires two additional parameters,which are the slope of the Hvorslev envelope and the structure parameter.The predicted results of structurally over-consolidated clays show that the proposed model can rationally describe the basic properties for structurally over-consolidated clays.
