  • This paper simulates the variation law of mechanical and hydraulic behavior unsaturated soils in the process of repetitively raining or evaporation. It establishes a hysteresis model on the basis of the basic principle of traditional domain model. The model is simple and can be easily adapted to programming. It is compared to some experimental data and other hysteresis models. The reliability of the proposed model is validated. The result demonstrates its good applicability in practice. Meanwhile, this model can be used as a basis in the research of the permeability and strength characteristic, together with the constitutive theories for unsaturated soils.
