摘要
为分析不同内排形态对边坡稳定性影响的机理,以蒙东某露天矿为例,基于理论分析结合数值模拟,以瑞典条分法为理论基础,揭示不同内排形态影响边坡稳定性的原因;并采用FLAC3D软件,模拟了不同排土距离、排土高度条件下边坡稳定性的变化情况,分析不同排土形态对边坡的位移、应变及稳定性的影响;最后得出内排压脚形态与边坡稳定性变化的一般规律。结果表明:内排形态影响内排重心分布,造成压帮边坡稳定性有所不同。
In order to analyze the mechanism of the influence of different internal dumping forms on slope stability,taking an open-pit mine in eastern Mongolia as an example,based on theoretical analysis,numerical simulation and Swedish slice method,this article reveals the reasons why different internal dumping forms affect slope stability.FLAC3Dsoftware is used to simulate the changes of slope stability under the conditions of different dumping distance and height,and analyze the effects of different dumping forms on slope displacement,strain and stability.Finally,the general law of the change of the internal discharge presser foot shape and slope stability is obtained.The results show that the internal dumping shape affects the distribution of the center of gravity of the internal discharge,resulting in different slope stability.
