摘要：
In this paper, a thermo-elasto-viscoplastic constitutive model is proposed to predict the one-dimensional consolidation behavior of clays under high temperature. In order to describe temperature and strain rate effects the proposed model is derived by introducing the temperature-dependent characteristics of volume change into the now surface history variable model of viscoplasticity. The applicability of the proposed modeling is examined by comparing analytical results with laboratory consolidation behavior under high temperature of clays using fully coupled thermal-hydraulic-mechanical simulation method. It is confirmed that the deformation behavior due to thermal loads and temperature history effects of clays can be expressed by the proposed thermo-elasto-viscoplastic consolidation model.
