通过抚顺西露天矿西帮人车卷边坡变形和滑坡分析,揭示了露天开采边坡失稳演变的过程;研究了边坡稳定系数衰减与位移速率变化两者间的关系;用灰色系统理论进行了边坡的滑坡预测。 Through the analysis of deformation and landslide analysis of the western slope of people and vehicles in Fushun West Open-pit Mine, the process of the instability evolution of open-pit slope was revealed. The relationship between slope stability coefficient attenuation and displacement rate change was studied. By using the gray system theory Landslide prediction was carried out on the slope.
