摘要
根据平朔安家岭露天矿工程实践,运用极限平衡理论的方法,借助Geo-Slope软件,进行了外部环境条件如地下水以及地下开采扰动条件下边坡稳定性影响的研究.考虑浸水影响并研究了地下开采扰动条件下的边坡破坏模式,最后进行了边坡稳定性的计算和评价,提出了相应的防治措施.结果表明:水压和地下开采扰动是影响边坡稳定性的重要因素,局部边坡受地下开采扰动十分剧烈,存在滑坡可能.
Chose the Anjialing open-pit mine in Pingshuo as research object, limit equilibrium theory and Geo - Slope software for slope stability analysis were utilized to consider the influence of external environment on slope stability, such as groundwater and underground mining. The contents of study included that studying water pressure and slope damage model under underground mining, and carrying out the slope stability calculations and evaluation, and providing with the corresponding prevention and control measures. Results show that the water pressure and underground mining are the important factors on affecting slope stability of the rock slope. Some upper slope are affected sharply, at the same time, the sliding of slope is possible.
