利用有限差分法，使用FLAC数值模拟软件来分析边坡稳定性。通过强度折减，当折减系数达到某一数值时，系统达到不稳定状态，边坡内一定幅值的总等效剪应变自坡底向坡顶贯通，认为边坡破坏。结合人工高填方边坡实例，FLAC程序通过不断改变承台的位置以及承台受力的大小，使边坡达到破坏状态，从而判断承台的临界位置和承台受力的临界大小。

This article brielfy introduces the basic principles of ifnite difference method, by which the stability of soil slope is analyzed using FLAC3D. When the strength reduction factor reaches a certain level, the slope system becomes unstable and some shear surfaces arise, which means the unstability of slope. Being explained with example of iflling slope, we change the position of pile caps and the stress on the pile to estimate the critical values by using FLAC3D.
