| 摘 要： | 识别岩土力学经验模型的关键是如何寻找到一个全局最优解。禁忌虎法是一种寻找全局最优解的算法。针对常规禁忌算法处理连续问题时搜索范围小，对初始点的依赖性强等不足，对算法进行了改进，并将禁忌算法的离散化过程进行了修改，提出了二阶段禁忌算法。用该算法对圆弧和楔体破坏边坡数模型中的参数进行了搜索。结果表明，该方法是一种行之有效的全局优化算法。

| Abstract: | The key of recognition of empirical geomechanical models is how to seek and find an global optimal solution.Tabu search is just one of effective algorthms for this.Considering the disadvantages of the very small searching area of conventional Tabu search and strong dependence upon initialization points at dealing with continuous problems,an improved tabu search algorithm was proposed.The parameters in the safety factor models for circular and failure slopes were searched by using the proposed algorithm.The results were compared with those of the maximum likelihood estimation.The algorithm proved to be powerful. |
