某白云岩矿露天边坡稳定性分析

Stability Analysis of Open-pit Slope of a Dolomite Rock Mine

为分析确定某白云岩矿露天采场边坡稳定性,将现有露天采场划分为四个分区,以定量分析为主,在划分的各个分区选择最具代表性的边坡剖面分别建立分析模型,对各分区的边坡整体稳定性进行分析计算。结果表明:Ⅳ分区高陡边坡稳定性较差,出现失稳破坏的可能性较大,其他分区边坡现状条件下比较稳定。

In order to analyse and determine open-pit mine site slope stability of a dolomite mine site,it has been classified four sections of existing open-pit mine site,and the analysis shall be mainly on quantitative basis,and analysis model has been established on the most representative slope profile selected on each of classified sections,and to conduct analyse to the slope stability of each sections.The results show thatⅣsection has a bad high steep slope stability,which has the most possibility of occurrence of loss of stability and destruction,and slope of other sections are comparatively stable under the existing conditions.
