摘　　要：高土石坝施工进度优化是一个复杂的非线性多目标综合优化问题,不仅需考虑施工资源投入及生产效率,更需要顾及大坝填筑质量和安全对施工进度的影响.在定量分析土石坝填筑质量、安全和进度相互关系的基础上,建立了高土石坝填筑质量-安全-进度综合优化模型,并针对传统优化方法的局限性,提出了该优化模型求解的遗传和声算法,实现了高土石坝填筑质量、大坝安全和施工进度的均衡安排.实例应用表明了本文方法的可行性,可为高土石坝施工进度计划优化与实时控制提供一条新的途径.Comprehensive optimization of high earth-rockfill dam construction schedule is a complex nonlinear multi-objective decision-making problem, which needs not only to consider the resources allocation and production effectiveness, but also to take into account the influence of compaction quality and dam safety on dam construction schedule. On the basis of quantitatively analyzing the relationship among compaction quality, dam safety and construction schedule, a comprehensive optimum model of the construction schedule coupling compaction quality and dam safety was established. To overcome the limitations of some traditional optimal methods, a genetic harmony search algorithm for the model was presented to achieve the best arrangement of the high earth-rockfill dam construction schedule with consideration of compaction quality and dam safety. Finally, a case study was given to prove the feasibility of the method mentioned above. It is shown that the method provided by the paper may be a new approach to optimizing and real-time controlling of high earth-rockfill dam construction schedules.
