某露天矿边坡稳定性研究及边坡结构参数优化
|
摘要
基于现场地质勘查和室内试验得到的数据,综合考虑了矿区的地层、构造、水文地质、工程地质等因素,应用极限平衡分析法对矿山边坡进行了稳定性分析。运用Geo-Slope和理正软件对边坡安全系数进行对比计算,并通过正交试验设计提出了终了边坡结构参数的优化方案,最终结果确定矿区终了边坡角为46.58°,为后续施工提供参考依据。
Based on the date obtained by geological survey on site and laboratory test,the mine geology,hydrology,earthquake and other factors were considered comprehensively,the limit equilibrium method was used to analyze and calculate the slope stability.Based on Geo-Slope and LiZheng software,the safety factor of slope was calculated and compared,and the optimization scheme for slope structure parameters was proposed on orthogonal experiment design.Finally,this study determined that the final pit slope angle was 46.58°,providing a reliable reference for the subsequent treatment of the mine slope.
