摘要

在土坡稳定的计算过程中常采用经典的极限平衡法。对每一条可能的圆弧滑动面通过条分法计算其安全系数，最小的安全系数就代表了土坡的实际安全系数。在此过程中，滑动面的圆心坐标和半径可以视为安全系数的函数，滑动面的圆心坐标和半径是自变量，安全系数就是函数值。这样，土坡安全系数的计算过程实际上是对安全系数这个函数求极值的过程。通过将土坡的安全系数视为圆心坐标和滑弧半径的函数，应用连续变量的禁忌搜索技术计算土坡稳定安全系数，提高土坡稳定计算的可靠性。

Abstract

Slope stability calculations are usually done in the framework of limit equilibrium analysis. Safety factors are calculated for every slip surface; and the lowest value of safety factor characterizes the safety of the entire slope. During the calculating process of slope stability safety factors are treated as function of the coordinates of the potential slip surface center and radius of the potential slip surface. By applying tabu search for continuous variables the safety factors of slope stability are calculated. The safety factor calculated by tabu search is globally optimal. Thus the reliability of slope stability calculation is improved.
