Landslide Stability Analysis Based on Improved Slice Method
In order to study the progressive failure process and stability evolution law of slope,two soil constitutive models were introduced on the basis of the traditional strip method,and a new strip method was established by combining deformation and force,and a new slope stabili-ty analysis method was proposed,which was described from the sliding surface point,sliding surface and sliding body in multiple dimen-sions,so as to effectively show the gradual failure process of landslide.The results show that the stability coefficient is 1.065 9 calculated by the traditional stability method,that is,the landslide is in an unstable state,combined with the analysis of the point-surface evaluation index of the landslide,in the process of the landslide moving forward in the critical state,the 29th block calculated by the strip method has a sud-den mutation,which proves that the landslide may suddenly fail after moving to the 29th block at the critical state point,and the calculation results of the ideal elastoplastic model and the shear stress model are compared and analyzed,and the strip method based on the shear stress constitutive model is closer to the force of the landslide,which can provide a reference for the monitoring and early warning of the landslide.
