Thermo-mechanical constitutive modeling of overconsolidated saturated clays

摘要

Using modified Cam-clay model and implementing a new approach to achieve deformation formulas, a thermo-mechanical model for saturated clays is presented in this paper. Proposed model does not include the required formulation for simulating changes in volume and pore pressure of soil in isotropic loading conditions which means that the model only predicts soil's response against deviatoric loading at fixed temperatures up to 100°C in conventional triaxial test condition. Results of modeling have been compared with some previous experimental data and validity of formulations is proved.
