摘　　要：以高西沟露天煤矿的西北边帮作为研究对象,运用FLAC3D数值模拟软件,经过数值计算得到边坡安全系数为1.57,其与工程类比法计算得到的数值差不多,知该数值分析方法不仅能快速、准确的算出边坡的稳定性系数,还能够形象的描绘边坡的滑移临界场,是一种有效的边坡稳定性分析的方法。Northwest side of open pit coal mine of Gao Xigou as the research object, it is put into the FLAC3 D numerical simulation software, through the numerical calculation for slope safety coefficient is 1.57, which is the same as the engineering analogy method for the calculation, and the numerical analysis method can not only quickly and accurately calculate the slope stability coefficient, but also describe the image of the critical sliding field, and it is a kind of effective slope stability analysis method.

关 键 词：露天边坡 FLAC3D 临界滑移场
