摘　　要：为提高基本和声搜索算法的全局搜索能力,提出了基于未知解空间探索与已知解空间开发相平衡的改进和声搜索算法。在基本和声搜索算法迭代一段时间后,在当前最好解的周围进行开发,所得的改进解反馈给基本和声搜索算法,继续进行迭代,如此反复,直至没有更好解产生为止。将新算法用于求解边坡最小安全系数,算例分析表明其效率比基本和声算法有较大提高。In order to improve overall search ability of basic harmony search algorithm,improved harmony search algorithm is put forward based on unknown solution space exploration and known solution space development.After a period of iteration of basic harmony search algorithm,exploration is carried out around the best solution and the improved solution obtained is fed back to basic harmony search algorithm for continuous iteration until no better solution is produced.This new algorithm is applied in searching for the minimum safety factor of side slope and it is indicated that its efficiency is much higher than that of basic harmony search algorithm.
