| 英文摘要 | A constitutive model for unsaturated soils is developed. Based on the SFG approach, the deduced LC curve has a smooth transition from saturated state to unsaturated state. The yield stress does not increase with increasing suction monotonically, and thus could reproduce plastic volume change of a slurry soil caused by drying. The model takes account of the effect of saturation, lead to different yield surface for wetting and drying. Soils with same suction but different saturation can have different yield stress. The model is used to simulate exited test data and the predicted curves agree well with the data points. |
