摘　　要：针对山地城市加压泵站多、造价高的特点,对传统的给水管网优化模型提出了改进,增加了中途加压泵站基建及运行管理费用,提出了符合山地城市分区管网特点的经济优化模型.并采用分层求解算法进行求解计算,将优化问题分解成两个子项,即布局优化子项和管径优化子项,最后通过工程实例验证了方法的实用性.Based on the characteristics of mountainous urban network, such as more booster pump station and expensive construction cost, traditional optimization model is improved. Operationand construction cost of booster pump station is added to optimization model. Then, optimization model of dividing districts towards mountainous urban network is presented. Because the model is complicated, this paper adopts method of decomposition coordination to get approximate solution. Finally, the result of optimization in Jiangnan District＇ s water supply project proved feasibility of the method.
