Simulation Analysis of Slope Stability Based on Strength Reduction

Article Preview

Abstract:

The characteristic of the stress and strain distribution of rock landslide are simulated by ANSYS finite element software, while its variation and distribution of plastic zone are analyzed by shear strength reduction method at the same time, which are used to search out the most dangerous slip surface. Calculation results show that: (1)Geotechnical landslide along the interface has decline; the stress increases by the depth of the slope and presents the layered distribution in the X, Y directions. (2)According to the contours of the plastic strain, the plastic strain contour ridge is the most dangerous slip surface. (3)Safety coefficients are offered by calculating the non-convergence, the maximum horizontal displacement and horizontal displacement of feature point mutation in slope failure criterion, to provide the basis for the landslide hazard warning.
