基于极限平衡法和FLAC^(3D)软件的高陡边坡稳定性分析

ANALYSIS ON STABILITY OF HIGH AND STEEP SLOPE BY LIMIT EQUILIBRIUM METHOD AND FLAC^(3D) SOFTWARE

某露天矿山设计终了边坡高度278～350m,坡角42～48°,属于典型高陡边坡。开采过程中出现了出现裂缝、下挫等现象。为了确保该矿山的安全生产,结合其地质资料及边坡的现状,本次选取了6个典型剖面,采用极限平衡法和FLAC^(3D)数值模拟软件,对该露天边坡进行稳定性分析,为后续边坡安全管理提供建议。

The end slope of an open-pit mine has a height of 278 ～350 m and a slope angle of 42 ～ 48°, which belongs to a typical high and steep slope. Combining with the geological survey data and the current situation of the open slope, six typical slopes are selected for slope stability analysis by using limit equilibrium method and FLAC^（3D） numerical simulation software in order to ensure the safe production of the mine. It comprehensively evaluates the stability of the open-pit slope to provide suggestions for slope safety management.
