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。

Abstract: 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.
