本文从排土场边坡岩石破坏模型入手,考虑到排土场形成的模拟,地震效应以及地下水的力学作用,采用弹塑性有限元分析方法对其边坡稳定性进行分析研究,并引入抗剪破坏安全度的概念,对边坡稳定性进行评价.应用于南芬铁矿庙儿沟排土场边坡稳定性研究,其计算结果与极限平衡分析结果进行了比较,取得良好效果,表明该方法具有广泛的应用前景.
This paper starts from the rock failure model of the dump slope and considers the simulation of the dump site, the earthquake effect and the mechanics of the groundwater. The elasto-plastic finite element method is used to analyze the stability of the slope, The concept of sabotage safety and the stability of the slope are evaluated.Study on the slope stability of the Miaolou dump in Nanfen Iron Mine shows that the calculated result is in good agreement with the results of the limit equilibrium analysis The method has a wide range of applications.
