摘要
为分析不同内排土场台阶结构参数对边坡稳定性影响规律,以某露天矿山边坡为研究对象,通过采用数值模拟软件,分析不同内排土场参数状态下边坡的位移、应变及稳定性变化情况及内排土场台阶参数对边坡整体稳定性影响的敏感性规律。结果表明:在内排土场反压边坡的工况下,内排土场台阶参数均会对边坡整体形变、稳定性产生显著影响,其中排土场台阶高度对矿山边坡整体稳定性影响最明显,台阶边坡角对矿山边坡位移影响最明显。
In order to analyze the influence law of different berm structure parameters of the internal dumping dump on the stability of the slope,the slope of an open-pit mine is taken as the research object.The influence of different internal berm parameters on the displacement,strain and stability change of the slope,and the sensitivity law of the internal berm step parameters on the overall stability of the slope are analyzed by using the numerical simulation software.The results show that under the working condition of the internal berm retarding the slope,the internal berm step parameters will have a significant effect on the overall deformation and stability of the slope.Among them,the height of the berm step has the most obvious effect on the overall stability of the open-pit mine slope,and the side slope angle of the step has the most obvious effect on the displacement of the open-pit mine slope.
