| 摘 要： | 裂隙性粘土是一种具有特殊性质的粘土，这种粘土边坡的破坏是渐进性的，传统的极限平衡法无法描述分析它的破坏过程和机理，也无法精确地判断它的长期稳定性。用FLAC程序对裂隙性粘土边坡的渐进性破坏过程进行了描述，算例表明在一定程度上用FLAC程序来模拟边坡渐进破坏和进行稳定性判断是可行的。

| Abstract: | Fissured clay is one kind of special clay. The failure of fissured clay slope is progressive. Traditional limit equilibrium method can not be used to simulate and analyze the process and mechanism of the slope progressive failure; and the judgment for long-term stability of slope is also not accurate. In this paper, the progressive failure process of fissured clay slope is simulated and the stability of slope is analyzed with FLAC code. The numerical analysis of an example shows that the simulation of the progressive failure of slope and the judgment for slope stability by FLAC code are feasible. |
