摘要
以山西朔州安家岭露天矿北端帮边坡为研究基础,对陷落柱影响条件下露天矿边坡变形破坏机理进行研究,确定了受陷落柱影响条件下边坡失稳变形破坏模式。利用以往地质及勘查资料,建立研究区边坡典型工程地质模型,运用有限元数值模拟研究方法研究其失稳变形破坏机理,采用极限平衡研究方法对研究区边坡进行稳定性评价,稳定性评价结果与变形破坏机理研究成果取得一致。
Based on the study of the north end slope of Anjialing open-pit mine in Shuozhou,Shanxi Province,the deformation and failure mechanism of open-pit slope under the influence of collapse column is studied,it is determined that the failure mode of slope failure under the influence of subsided column.Based on the previous geological and exploration data,the typical engineering geological model of the slope in the study area is established,the failure mechanism of the slope is studied by using the finite element numerical simulation method,the slope stability in the study area is evaluated by using the limit equilibrium method,the results of the stability evaluation are consistent with those of the deformation and failure mechanism research.
