SLOPE/W在某露天煤矿采掘场边坡稳定性分析中的应用

某煤矿采掘场非工作帮边坡为软岩高边坡,为分析边坡是否存在潜在安全隐患而影响施工进度及施工安全,进行了非工作帮边坡的稳定性分析。采用Geo-studio软件中的Slope/W模块建立了边坡的计算模型,并用Bishop法和Morgenstern-price法对暴雨工况和暴雨叠加地震工况进行计算,得出边坡的稳定性系数。推测的滑面计算结果与边坡稳定性评价的标准进行对比,发现计算结果与现场勘察后预测结论基本一致。该边坡整体稳定性为基本稳定。更多还原

Application of SLOPEP/W in Slope Stability Analysis of an Open Pit Mining Field

The nonworking slope of a coal mining field is a high soft rocky slope.In order to analyze the slope whether there is a potential security risk to affect the construction schedule and construction safety,the stability of the nonworking slope is analyzed.The computational model of the slope is established with the Slope/W module in Geo-studio software,the rainstorm working condition and heavy rain superposition seism condition are calculated with Bishop and Morgenstern-price method,and the stability factor of the slope is obtained.Finally,compared the calculation results of the speculated sliding surface with the slope stability assessment standards,it is found that the calculation results and site survey forecasting conclusions are basically the same.The whole stability of the slope is basically stable.
