摘要
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。
The FLAG3D software was used to make a stability analysis of an integral slope excavation, the open- cast mine was divided into three zones according to the rock structure and landform. The finite difference model was established separately for each zone slope,by changing the excavation slope angle and calculating the slope stability safety factors at different angle, the optimum slope excavation angle was determined. Finally, the integral excavation analysis of the three zone slopes was given based on the optimum excavation angle, the integral stability of the mine slope was evaluated comprehensively, and the safety factors of the corresponding slope were worked out.
