摘要
随着国内外露天开采技术的迅速发展,露天开采的深度和规模日益增大,露天边坡的稳定性和安全性越来越差,对边坡进行稳定性分析及治理设计显得尤为重要。针对研究区边坡的稳定性进行定性和定量分析,其中定量分析采用刚体极限平衡法中的瑞典条分法,通过定性与定量分析确定其稳定状态,并采用削坡、坡脚回填和设置排水沟等方式对不稳定的东侧边坡进行治理设计。
With the rapid development of open-pit mining technology at home and abroad,the depth and scale of open-pit mining are increasing,and the stability and safety of open-air slopes are getting worse and worse.It is particularly important to analyze the stability and design of slopes.This paper mainly conducts qualitative and quantitative analysis of the stability of the slope of the study area.The quantitative analysis uses the Swedish strip method in the rigid body limit equilibrium method to determine its steady state through qualitative and quantitative analysis,and adopts slope cutting and slope backfilling.And the way of setting the drainage ditch to control the unstable east side slope.
