摘　　要：针对FLAC3D后处理暂无法定量直观反映岩体破坏状态的问题,采用Mohr圆理论,对某矿4个连续开采步的稳定性进行了FLAC3D模拟分析。研究结果表明,利用Mohr圆反映岩体的稳定性状态,既简单直观,又方便有效,很好地解决了FLAC3D中Mohr-Coulomb准则不能直观、定量反映岩体稳定性状态的难题。Aiming at the problem which the post - procession of FLAG^3D could not intuitively and quantificationally show failure state of rock mass, the rock stability of four continuous mining steps in a mine was simulated with FLAC^3D based on Mohr circle theory. The studied results showed that Mohr circle is intuitionistic, convenient and effective in reflecting the stability of rock mass. The study has solved commendably the difficult problem which the stability state of rock mass cant be showed by Mohr - Coulomb criterion in FLAC^3D .
