| 摘 要： | 为了得到巴基斯坦山达克铜金矿露天边坡最优参数,选取了8个工程地质剖面,通过极限平衡分析了A～H剖面在三种工况下的安全系数。基于设计参数,对8个边坡剖面进行计算分析,得出了边坡各剖面最优边坡角结构参数,并根据工程地质分区,推荐各分区边坡结构参数如下:1)A、B、C、E、F、G剖面整体边坡角为46°,即Ⅰ区、Ⅲ区边坡整体边坡角46°;2)D、H剖面整体边坡角为45°,即Ⅱ区、Ⅳ区边坡整体边坡角45°。

| Abstract: | In order to obtain the optimal parameters of the open-pit slope in Sandak copper gold mine, Pakistan, 8 engineering geological sections are selected, and the safety factors of A-H section under three working conditions are obtained through limit equilibrium analysis. Based on the design parameters, 8 slope sections are calculated and analyzed, and the optimal slope angle structure parameters of each section are obtained. According to the engineering geological division, the recommended slope structure parameters of each section are as follows: (1) the recommended overall slope angle of section A, B, C, E, F, G is 46 °. The recommended overall slope angle of section I and III is 46 °. (2) the recommended overall slope angle of Section D and H is 45 °. The 45 ° is recommended for the overall slope angle of zone II and IV. |
