摘要： 与极限平衡分析方法相比，采用有限元分析边坡稳定性具有一定的优点，通过将有限元分析与禁忌搜索结合，计算边坡安全系数并同时确定其对应的最危险滑动面，既发挥了有限元在数值分析方面的优越特性，又利用了极限平衡的思想，同时，还充分展拓了禁忌搜索的全局搜索能力。算例分析表明，该方法是可行的，在边坡稳定性分析中具有很好的应用前景。

Abstract: Compared with the limit equilibrium method for analyzing slope stability, the finite element method (FEM) has its own advantage when it combined with Tabu search. Because of their combination, the safety factor of slope is calculated meanwhile the most dangerous sliding surface is also determined, in which it reflects not only the advantage of FEM for its numerical analysis but also the identification of limit equilibrium, particularly the global searching ability of Tabu search is fully utilized. The example shows its feasibility, which implies the finite element method with Tabu search has the bright future of application for analyzing slope stability.
