| 摘 要： | 综合分析了影响露天矿边坡稳定性的主要因素,通过对3种基于极限平衡理论(Limit-Equilibrium)的边坡稳定分析软件在岩土质边坡稳定性分析中的实际操作,表明用BishopGS法计算得到的安全系数在大多数情况下较稳定。工程技术人员应结合矿情,科学有效地确定露天矿边坡的最佳许用安全系数。

Evaluation Method of Slope Stability Based on Limit-equilibrium Theory |

| Abstract: | The principal factors affecting slope stability in open-pit mines were analyzed synthetically, and the actual application of several slope stability analysis software which were based on Limit-Equilibrium theory showed that the safety coefficients that were calculated by BishopGS method were more stable in most cases. The engineering technicians should scientifically and effectively confirm the optimum allowable safety coefficients for the slope of the open-pit mine according to the actual situation of the mine. |
