摘要
针对堆石坝料物调运规划对料物调运总运距和高峰期运输强度等目标的影响,建立了堆石坝料物调运多目标动态优化模型,提出了模型的解法,并将模型应用于实际工程中,在料物调运方面很好地优化了工程的经济和技术指标。实践证明模型是可行的、有效的。
Based on systematical analyzing the characteristics of transportation balancing of earthwork and the dynamically changing of road in the rockfill dam construction and those influences on the total transportation distance and the transportation intensity, a method is prompted to solve the dynamic optimization of material planning, which disperses the dynamic construction course into a lot of stages. Further, a multiobjective dynamic optimization model of material planning is established, and then a solution of the model is presented. An example whose targets of economy and technology is optimized in one project is given to show that the model is applicable and effective.
