摘要
针对厄立特里亚的科卡露天金矿边坡工程的稳定性进行分析,选取了代表性的三个剖面,采用极限平衡法和有限元强度折减法进行计算。结果表明:极限平衡法计算得到的三个剖面中最小的安全系数为1.46,而有限元强度折减法获得最小安全系数为1.45。安全系数均满足国家技术规范要求,初步设计的露天矿边坡处于稳定状态。
In this paper, the slope stability analysis of open pit gold mine in Eritrea was carried out. Three representative crosssections were selected. The limit equilibrium method and finite element strength reduction were used to calculate the factor of safety of the slope. The results showed that the minimum factor of safety of three sections by limit equilibrium method is 1.46, while that by the finite element strength reduction is 1.45. The factor of safety of the slope meets the national technical specifications, and the open pit slope designed preliminarily is in a stable state.
