应用FLAC3D软件对某矿山边坡进行整体开挖稳定性分析,根据岩体结构和地貌形态将该露天矿山边坡划分为3个区,分别对每区边坡建立有限差分模型,通过变换开挖边坡角度,计算不同角度下边坡的稳定安全系数,确定边坡的最佳开挖角度,最后根据最佳开挖角度将三区边坡进行整体开挖分析,对该矿山边坡的整体稳定性进行综合评价,得出相应的边坡稳定性的安全系数。 FLAC3D software was used to analyze the stability of a mine slope. According to the structure and topography of the rock mass, the open pit slope was divided into three zones. The finite difference model was established for each slope in each zone. Excavation Slope angle, the stability safety factor of slope under different angles is calculated and the optimal excavation angle of slope is determined. Finally, according to the best excavation angle, the excavation and analysis of the three areas of slope are conducted, and the overall stability of the slope Comprehensive evaluation of sex, draw the corresponding slope stability of the safety factor.
