| 摘 要： | 通过对一个软岩边坡进行FLAC和刚体极限平衡方法的对比分析,来论证这两种方法的适用性.FLAC能大致确定出坡体最自然的破坏方式、不稳定区域及其运动趋势,考虑的是边坡整体的安全程度.刚体极限平衡分析则需要人为指定或使用软件搜索不稳定范围,考虑的仅是不稳定面上的安全度,不易判别边坡最可能的剪出方式. |

| Abstract: | A weakrock slope's stability is analyzed with the FLAC & limit equilibrium method(LEM),then the suitability of them are evaluated. FLAC method can approximately ascertain a slope's natural failure mode and its unstable zones. It also can forecasts the kinetic trend and thinks over whole slope's degree of safety. In the process of calculation,the LEM need the slide region designated by handiwork. The LEM only thinks over the slip surface's degree of safety and this made it difficult to judge the destruct reg... |
