摘要

A constitutive, non-isothermal unified hardening (UH) model is presented to interpret the thermo-elastoplastic behaviours of normally consolidated (NC) and overconsolidated (OC) clays. Two yield surfaces (the current yield surface and the reference yield surface) are adopted in the proposed model.A unified hardening parameter (H) is developed to describe the evolution of the current yield surface, and the plastic volumetric strain is employed to quantify the hardening of the reference yield surface. The similarity ratio (RT ) between the current yield surface and the reference yield surface, which is a function of the temperature and plastic volumetric strain, is developed to govern the volume change behaviour and the shear strength of soils with different stress histories and at varying temperatures. The proposed model is then validated through test results in the literature.
