FORMING AND DEVELOPMENT PROCESS OF SOIL LANDSLIDE DURING RAINFALL
降雨条件下土体滑坡的有限元数值分析

Duncan-Chang model is introduced into the constitutive relationship of saturated-unsaturated soils,and the nonlinear elastic model for this kind of soils is established,and is used for the analysis on the landslide during rainfall. Example analysis shows that it is feasible and beneficial to use this model for the analysis of soil landslide during rainfall.
