| 摘 要： | 针对土坡非圆临界滑动面的确定问题，提出了一种两点直线搜索策略替换随机搜索策略，以最大限度地利用和声库的积累信息搜索新解。以一种修复策略替换惩罚策略来修复搜索过程中可能出现的不合理滑动面，更有效地搜索最危险的滑动面，而构成了一种新的和声搜索算法，给出了利用新的和声搜索算法求解两个土坡最小安全系数及其临界滑动面，与已有的结果比较，证明了提出的两种策略是有效合理的。

| Abstract: | A new harmony search method is presented in the location of non-circular slip surface of soil slopes. It differs from the basic harmony search method in the flowing two aspects. Firstly, a kind of two-point search strategy rather than random search strategy is adopted to take full advantage of the accumulated information in the harmony memory. Secondly, a correcting strategy is substituted for the penalty strategy to render the inadmissible slip surfaces to be acceptable. The stability analyses of two soil slopes are evaluated by the new harmony search method. Comparisons between the existed results and the results from the new harmony search method indicate that the proposed strategies are valid and rational. |
