摘要: 针对隐伏单空区露天边坡稳定性采用传统分析无法定量、直观反映岩体破坏状态的缺点,运用Mohr圆理论,模拟并分析某露天矿边坡下赋存5种不同位置的隐伏单空区对边坡稳定性的影响。研究表明:露天边坡下隐伏单空区的顶板是空区最薄弱区域,隐伏单空区距边坡的距离越远边坡相对比较稳定。  

关键词: 露天边坡, 隐伏单空区, Mohr圆, 稳定性

Abstract: Aiming at the traditional analysis of open pit slope stability under condition of concealed single gap could not reflected rock damage state quantitatively and intuitively, influences of 5 different position concealed single gap below a open-pit slope to slope stability were simulated and analyzed by using Mohr circle. The research indicated, roof of concealed single gap of open pit slope was the weakest area in gap, slope was much stable with the distance much longer between concealed single gap to slope.

Key words: Open pit slope, Concealed single gap, Mohr circle, Stability
