强度折减法的边坡稳定性分析——以尾矿库右岸坝肩边坡为例

Slope Stability Analysis Based on Strength Reduction Method——Taking the Abutment Slope of the Right Bank of Tailings Reservoir as an Example

矿山工程边坡稳定性是影响安全生产的重要因素之一。本文以云南某尾矿库右岸坝肩废石土边坡为例,简单介绍了强度折减有限元法,并基于大型有限元分析软件Ansys,利用强度折减法对该边坡进行具体分析,并绘制塑性应变云图。结果表明该边坡处于不稳定状态,有待治理,对不稳定边坡提出了合理的治理意见。

The slope stability of mining engineering is one of the important factors affecting safe production.Taking the waste rock slope of the right bank abutment of a tailings pond in Yunnan as an example,the strength reduction finite element method is briefly introduced,and the slope is analyzed by the strength reduction method based on the large finite element analysis software Ansys.Draw a plastic strain cloud map.The results show that the slope is in an unstable state and needs to be treated,and reasonable management opinions are put forward for the unstable slope.
