| 摘 要： | 顺倾弱层对露天矿开采边坡稳定性影响很大,尤其存在相邻顺倾弱层条件下边坡稳定性问题更加复杂,且对稳定性影响的研究难度更大。采用有限元数值模拟的计算方法,对含相邻顺倾弱层的露天矿开采边坡进行稳定分析,得到露天矿开采过程中边坡岩体应力状态和边坡变形运动趋势,研究结果为露天矿开采边坡稳定性评价提供可靠依据。

| Abstract: | The cis dumping weak layer has a large influence of open-pit mining slope stability,especially at the weak layer adjacent cis dumping,the slope stability problem is more complex,and study on the influence of stability is more difficult,The open-pit mining slope stability containing adjacent cis dumping weak layer is analyzed by the finite element numerical simulation,the open-pit mining process,the slope rock mass stress state and slope deformation movement trends are received,the findings can provide a reliable basis for open mining slope stability evaluation. |
