The thermomechanical approach to establishing elastic/plastic constitutive model for geomaterials not only has a tight mathematical structure, but also satisfies the laws of thermo-dynamics automatically and has a rigorous mathematic and physical basis. The isotropic thermomechanical model proposed by Collins (2002, 2005a) is introduced briefly and analyzed in detail. Aiming at its shortage of hardening law, the unified hardening parameter is incorporated into this model. And then, the model is extended to a unified thermomechanical model for soil which can be applied to both clay and sand. The FEM computer program of thermomechanical model and improved unified model are worked out. The adaptability and validity of improved model can be seen from the comparison and analysis of calculated results.
