摘　　要：为了解决露天与地下复合开采条件下的边坡稳定性问题,通过有限元数值模拟分析地下开采下露天矿边坡中的应力、位移场,损伤,探讨了地下开采对边坡稳定性的影响。采用国际上比较流行的大型有限元分析软件ABAQUS,结果表明,此方法不仅适用地下与露天复合开采条件下的边坡稳定性的评价,同样也适用于地下开采对丘陵山区斜坡体、铁路路基稳定性的评价。To address the open and underground mining complex problems of slope stability under the conditions,through the finite element numerical simulation analysis under the underground mining of open pit slope of the stress,displacement,injury,of the underground mining on the stability of slopes.Use of internationally popular finite element analysis software ABAQUS,the results show that this method is applicable not only to mining conditions underground and open-air complex evaluation of slope stability under the same applies to underground mining in the body of the hills and mountains slopes,the railway embankment stability Of evaluation.
