在判断露天矿边坡稳定与否时进行定量评价显然是很重要的，并由此定量评价作出某种决定。本文给出了含有不同岩层的露无矿在平面滑坡情况下的最终稳定分析和灵敏度分析。该方法是圆弧滑坡方法（圆弧法）和平面滑坡方法（平面法）的结合。在本文研究中，讨论了参数对边坡稳定性的影响并提出了一些修正措施。
It is obviously important to make a quantitative assessment of the stability of the open pit slope or not and to make a quantitative decision. In this paper, the final stability analysis and sensitivity analysis of dew-free ore mines with different rock formations in the case of plane landslide are given. This method is a combination of the circular landslide method (arc method) and the plane landslide method (plane method). In this paper, the influence of parameters on slope stability is discussed and some corrective measures are proposed.
