极限平衡法与有限元法相结合的露天矿山边坡稳定性分析

Stability Analysis of Open-pit Slope by Combining Limit Equilibrium Method and Finite Element Method

矿山边坡稳定性评估常用的极限平衡法虽计算简便,但计算过程对边坡破坏模型进行了简化,导致计算精度不高,而有限元法充分考虑了露天矿山边坡的破坏模式,能够有效弥补极限平衡法的缺点。将极限平衡法与有限元法结合,综合确定矿山边坡的稳定性,为矿山边坡设计与稳定性评估提供理论依据。

Evaluation for slope stability of mines by means of common limit equilibrium method is simple in calculation,but the calculation process simplifies slope damage model,leading to low calculating accuracy.However,by finite element method,damage modes of open-pit slopes are fully taken into account of and this method can effectively compensate for disadvantages of limit equilibrium method.By combining limit equilibrium method and finite element method,stability of mine slopes is determined comprehensively,which provides theoretical basis for design and stability evaluation of mine slopes。
