ABAQUS强度折减法分析边坡稳定性影响因素
Analysis of Slope Stability's Factors by Using ABAQUS Based on Shear Strength Reduction Method
摘要
Abstract
The basic principle of shear strength reduction method is introduced. In the process of numerical a-nalysis, we recommend convergence of displacement calculation as the standard of slope reaches limit equilibrium state; and use ABAQUS finite element analysis software and finite element method to figure out the stability of the slope which contains the soft substratum, and analyse the influences of elastic modulus, Poisson' s ratio, density and shear strength of the upper and lower soft soils on the stability of the slope. From above analysis, a conclusion is drawn as follows: the soil's shear strength and density have a remarkable effect on the slope's stability and the formation of landslide; while Poisson's ratio and elastic modulus have a little impact.关键词
