摘　　要：通过1∶50000地质灾害风险调查,总结出铜陵地区露采高陡五通组上段中薄层状含泥质粉砂岩顺层岩质边坡的孕灾结构特征和破坏机理。该类边坡因D_(3)w/C_(2+3)层间滑脱断层和开采卸荷作用,岩体裂隙发育,工程地质条件差,降雨入渗易诱发软弱结构面贯通,发生变形、滑坡,对下游居民与企业的安全造成严重威胁。本文以典型灾害点五峰山滑坡为例,在分析滑坡体结构特征与稳定性的基础上,开展不同的治理方法研究,并进行优化对比,以期为其他地区该类型滑坡的防治提供借鉴。Based on 1∶50000 geological hazard risk survey,this paper has summarized the hazard-inducing structure and failure mechanism of the mid-thin layered argillic siltstone slope along a bedding plane in the upper member of the Wutong Formation,high and steep in the open pit,in the Tongling area.Due to D_(3)w/C_(2+3) inter-layer detachment fault and mining-induced unloading,rock cracks develop in the slope,and the engineering geological conditions are poor,and rainfall infiltration usually finds itsway along theweak structural plane,inducing deformation and landslide,which poses a serious threat to the safety of downstream residents and enterprises.Taking the Wufengshan landslide as an example,on the basis of analyzing the structural characteristics and stability of the landslide,different treatment methods are studied and compared,in order to provide a reference for the prevention and control of this type of landslide in other areas.
