摘　　要：软弱夹层或软弱结构面的存在,引起边坡蠕动变形破坏,威胁露天矿边坡稳定。通过探讨含软弱夹层边坡的破坏机理,分析含软弱夹层边坡的破坏形式,并结合矿山实际情况,运用ANSYS软件,建立含有软弱夹层的露天矿边坡体模型,并通过有效数据进行分析,确定该露天矿边坡体是否稳定,从而确定软弱夹层对露天矿边坡稳定的重大影响。在工程实践中,应详细查明软弱层位置,提早制定有效的边坡防护措施。Weak interlayer or weak structural surface will cause creep deformation and damage because they exist in the open pit,and this will threaten the open-pit slope stability.The destruction of the slope with the form of soft interlayer through its failure mechanism was discussed.According to the studies of mining case,the model of open-pit slope with the weak interlayer was established using ANSYS software.Through the analysis of effective data and the observation of test results,it can determine its stability.The weak interlayer has a great influence on slope stability.
