Abstract 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.

Key words： saturated-unsaturated soils nonlinear elastic model Duncan-Chang model landslide
