保持边坡稳定是露天矿生产经营的一项重要内容。为确定双利铁矿2号露天采场扩帮后的最终边坡角，通过运用FLAC3D软件建模分析边坡的应力分布、位移移动趋势、弹塑性区分布以及有限元强度折减法计算边坡的安全系数，从而确定合理的边坡角，并为后期边坡的监测提供参考依据。

Keeping the slope stability is important in the operation of open-pit mining.In order to determine the fi-nal open-pit slope angle in No.2 open-pit mine in Shuangli Iron Mine after the expansion,the stress distribution and displacement distribution,elastic and plastic zone distribution are analyzed by FLAC3D and the safety coefficient of the slope calculated by finite element strength reduction.Reasonable slope angle is determined and a reference basis is provided for late slope monitoring.
