【摘要】 针对露天边坡下存在隐伏多空区的工程情况,采用AutoCAD、ANSYS和FLAC3D三套软件各自的优点联合建立了露天隐伏多空区边坡三维模型,借助Mohr圆破坏理论可以直观、有效的得出反映边坡稳定性状态的特点,分析了两种不同位置情况下隐伏多空区对露天边坡的影响,研究表明:当隐伏多空区位于边坡岩体上部时会因拉应力达到极限状态而失稳;当隐伏多空区位于边坡岩体下部时相对比较稳定。更多还原

【Abstract】 For the engineering of the concealed goaf under the open slope,a three-dimensional model of the concealed goaf slop was created using AutoCAD,ANSYS and FLAC3D with their respective advantages.The influences of concealed goaf slop under conditions of two different locations were analyzed utilizing Mohr circle which is intuitive and efficient to teflect the state of slope stability.The research shows that the open slope is unstable when the concealed goaf locates the upper open slope.A relative stable slope exists when the concealed goaf locates in the lower part of open slope.更多还原
