安家岭矿高陡边坡滑动破坏机理分析

Analysis of failure mechanism of high and steep slope in Anjialing mine

本文以安家岭露天矿北端帮边坡为研究对象,根据实际工程情况和工程需要对其典型边坡进行滑坡破坏的稳定性分析和破坏演化机理研究。根据边坡滑动破坏前和破坏后的稳定性计算结果和仿真模拟的破坏规律分析结论,提出了相应的治理方案,并进行了治理后的边坡稳定性计算和数值模拟分析。由计算分析结果可以看出,按此方案治理后的边坡,稳定性安全储备达到要求,边坡的破坏场得到控制,位移基本稳定,边坡整体稳定能够满足生活、生产的各种要求。

The object of study in this paper is the northmost part of strip slope in Anjialing mine,and the stability analyses and the destruction evolution mechanism for the landslide destruction of typical side slope has been studied according to the actual situation and demand.what′s more,this article has also introduced the corresponding plan for government and carried stability computation and the numerical simulation analysis of side slope which has been processed according to result of stability computation and principle of simulated destruction not only after the slope destroyed but also before. It is easy to learn from the result of computation analysis after this slope has been processed that the stable safety meets the requirements, the side slope destruction field is under controlled, the displacement is stable basically and the whole stability can satisfy the varied requirements both on life and production .
