摘要
以白云鄂博铁矿主矿露天采场+1 230 m以上南部边坡为工程背景,运用极限平衡法计算出边坡在自然、地下水和地震3种不同组合工况下的安全稳定系数,并通过Flac3D软件分析了边坡的应力、应变、位移变化规律,最后得出了E1、D1、D2区的稳定边坡角。
With the southern slopes above ＋ 1 230 m of open stope of the main mine in Baiyun＇ebo Iron Mine as engineering background,the limit equilibrium method is adopted to calculate the safety factors under three different combined conditions of the nature,the groundwater and the seismic,and the variation law of stress,strain,displacement is analyzed based on Flac3D.Then,the slope angles of stability for region E1,D1,D2 are finally obtained.
