摘要
阐述了有限元强度折减法的基本原理,利用强度折减法对尾矿坝进行了边坡稳定计算,同时通过简化毕肖普法和瑞典圆弧法对其结果进行了对比分析,证明基于有限元理论的强度折减法的计算结果是可信的,其安全系数值可以作为定量判断的依据。
This article elaborates the principle of FEM strength reduction.By using the strength reduction method,it makes a slop stability calculation to tailing dam,at the same time it makes a comparative analysis to the result by simplified Bishop Method and Sweden Arc Method.The result shows that the calculation result based on the theory of finite element strength reduction is reliable and its safety factor can be used as a quantitative basis for judgment.
