The landslide thrust force is an important element in landslide treatment design.With the landslide residual pushing force curve,mechanical parameters of landslide can be analyzed in inverse method.According to the different forms of residual pushing force curve,different treatment designs were proposed,which can be used in landslide treatment design. The landslide project practice shows that this method is more convenient and intuitional.

Due to the variation of rocks,it is important to choose the landslide mechanical parameters accurately and have a sensitivity analysis on mechanical parameters.A case study of the landslide around the previous government office in Huangxi Town in Chongqing is carried out.In the case study,the influence factors are found out according to the parameters sensitivity analysis;and then synthesize the indoor and outdoor experimental data as well as the results of parameters inverse calculation,the reasonable landslide mechanical parameters are selected by using "integrated method of parameters value". The practice has proved that this method has a good practical value in engineering.
