摘要
为分析某露天矿坑内排土场边坡稳定性,先采用极限平衡法中的瑞典法、简化毕肖普法、推力传递法、滑楔法、摩根斯法计算边坡安全系数,然后采用数值模拟软件FLAC^(3D)模拟边坡岩土体的应力及位移的变化规律.通过对所得边坡安全系数、应力及位移结果进行分析可知,该排土场边坡处于稳定状态.
The limit equilibrium methods including Swedish slice method, simplified Bishop method, pushing method, wedge method and Morgenstern-Price method were adopted to calculate the safety factors for the slope, and then the numerical simulation software, FLAC^3D , was adopted to simulate the regular of stress and displacement for analyzing the stability of waste dump slope in an open mining pit. It can suggest that the slope of waste dump be in a steady state according to the analysis of the slope safety factors, stress and displacement
