摘　　要：太钢袁家村铁矿现已出露的土质边坡位于采场西北区域,属于临时边坡。该文以土质边坡为研究对象,根据钻孔地质情况,建立了三维钻孔模型。通过对岩芯及试样进行测验,获得边坡稳定性分析所需的岩土体物理力学参数。采用简化毕肖普法、摩根斯坦-普莱斯法和简布法三种方法,对土质边坡在现状和终了状态下的稳定性进行评价。根据评价结果,采用削坡减载、放缓坡度的技术措施,优化原有边坡设计方案,动态调整边坡参数,确保边坡稳定和采矿安全生产。该研究方法可为其它土质边坡的稳定性研究提供参考。The exposed soil slope of Yuanjiacun iron mine of Taiyuan Iron and Steel Group Co.,Ltd.,located in the northwest area of the stope,is a temporary slope.Taking the soil slope as the research object,a 3D borehole model is established based on the geological condition of boreholes.The physical and mechanical parameters of rock and soil mass required for slope stability analysis are obtained by testing core and samples.The stability of soil slope in present and final state is evaluated by using three methods:simplified Bishop method,Morgenstern-Price method and Janbu method.According to the evaluation results,load reduction by slope trimming,and slope angle adjustments are adopted to optimize the original slope design scheme and dynamically adjust slope parameters in order to ensure slope stability and mining operation safety.This research method provides reference for the stability analysis of similar soil slopes.
