| 摘 要： | 针对安太堡露天矿内排土场边坡,介绍了边坡的工程概况和地质条件.结合边坡工程的具体特点,首先运用SLIDE软件,对不同工况下边坡强度稳定性进行对比分析,进而对位移监测数据发展趋势进行了研究.结果表明：排土场边坡的变形处于不断发展的过程中,在降雨或地震的作用下排土场边坡稳定系数明显降低,可能滑动面扩大,特别是在降雨条件下局部危险滑动面可能发生贯通,边坡存在整体失稳的可能.通过研究,可为排土场边坡综合治理措施的制定提供依据.

| Abstract: | According to the dump slope engineering of Antaibao open-pit mine,the engineering background and geological conditions are introduced.Combined with the characteristics of the slope engineering,SLIDE software is used to analyze slope stability under different working conditions,and then the development trend of the displacement monitoring data is studied.The results show that the deformation of dump slope is in a continuous process of development.In rainfall or under the earthquake,slope stability coefficient reduces significantly,and sliding surface expands largely.In rainfall,dangerous sliding surfaces are possible to connect with each other,and whole instability may occur.Through the study,it can provide guidance for the protection and control of dump slope. |
