摘　　要：保证边坡的安全稳定,对于生产施工设备以及人员生命安全具有重要的作用。为保障新疆富蕴县蒙库铁矿南帮露天边坡的安全,对南帮边坡开展了室内室外岩体参数力学试验,采用极限平衡法对边坡剖面进行了稳定性计算。结果表明:南帮边坡稳定性系数不符合相关规范,具有产生滑坡的风险。因此对易滑区域采用锚索(杆)框架梁结构体系进行综合治理,并对治理后的区域利用极限平衡法进行稳定性分析,认为在经过治理后的南帮边坡稳定性系数显著提升且符合相关规范要求。锚索(杆)框架梁结构体系对于类似的矿山边坡治理具有一定的参考作用。Ensuring the safety and stability of slope plays an important role in the safety of produc⁃tion and construction equipment and personnel.In order to ensure the safety of the south open-pit slope of Mengku Iron Mine in Fuyun County in Xinjiang,the indoor and outdoor mechanical tests of rock mass pa⁃rameters were carried out on the south slope,and the limit equilibrium method was used to calculate the sta⁃bility of the slope profile.The results show that the stability coefficient of the south slope does not conform to the relevant specifications and has the risk of landslide.Therefore,the anchor cable(rod)frame beam structure system was used for comprehensive treatment of the slippery area,and the limit equilibrium meth⁃od was used to analyze the stability of the treated area.The calculation results show that the stability coeffi⁃cient of the southern slope after treatment is significantly improved and conforms to the relevant specifica⁃tions.The anchor cable(bar)frame beam structure system has a certain reference function for similar mine slope treatment.
