露天采场边坡稳定性的有限元数值模拟分析

摘要

本文针对国内某露天采场边坡，根据其岩体力学参数，运用有限元数值模拟对其进行边坡稳定性分析，研究了边坡的破坏区分布，在分析滑动机理时，通过不同强度折减系数计算出边坡内最大剪应变发展状况，得出边坡变形破坏的首要部位将为坡脚，其次为坡顶，滑面形状为近似圆弧形，并得出了其破坏机理。%This paper uses finite element numerical simulation to analyze its slope stability of a domestic open pit slope, according to the rock mechanical parameters, studies the distribution of the slope failure zone, in the analysis of sliding mechanism, by different strength reduction factor to calculate the slope of the maximum shear strain development, obtains that the primary site of the toe of slope deformation and failure will be followed by a hill, slippery surface shape is approximately circular shape, and draws its failure mechanism.
