Study on the inversion of shear strength parameters of rainfall-type landslide
Taking the Shuping landslide in the Three Gorges Reservoir area as an example,and based on the comprehensive analysis of the relationship between the displacement varia-tion characteristics of rainfall-type landslide and the dynamic factors of rainfall,this study proposes a comprehensive inversion measurement and calculation method for determining the shear strength parameters of the slope according to the grey correlation theory.The pro-posed method overcomes some limitations of traditional measuring method,including that the test sample quantity is small,the test result of a small sample size replaces the whole slope shear strength parameter selection,and the test cost is high.In addition,the steps of the new method are easy to handle,and the computation cost is low compared with other methods.The value of slope shear strength parameters can be obtained through calculation and the calculation results are more representative of the whole slope parameter selection.The authenticity and feasibility of this method in selecting rainfall-type landslide shear strength parameters is verified.
