摘　　要：通过引入混沌扰动算子增加解的多样性和提高全局寻优能力,另外通过构造蚂蚁的启发式搜索方式提高对局部最优解的搜索能力,从而有效地克服了基本蚁群算法容易出现停滞和搜索效率低的缺陷。还利用Spencer法和Janbu法,探讨了所提出的具有混沌扰动算子启发式蚁群算法在边坡稳定性分析中的应用。实例计算和对比分析结果表明,该法有效而又可靠。The chaos operator is introduced into the basic ant colony algorithm for enhancing the variety of solutions and the ability to find global optimization solution, and the heuristic search pattern is established to increase the computing efficiency of local optimization solution. Thus, the phenomena of stagnation existing in basic ant colony algorithm is avoided and the search performance is considerably improved. The application of heuristic ant colony algorithm involving chaos operator to the analysis of slope stability is discussed based on Spencer's slice method and Janbu's slice method. A case study is given to verify the proposed method. The results show that the proposed algorithm is practical and reliable.
