摘要
在供水规划中,管网设计是重要的组成部分,为了降低管网建成后的漏损及运行费用,需要在规划设计阶段对管网进行水力平差计算。针对规划管网水力平差的特点,提出应用GIS的分析功能及EPANET水力计算软件构建管网的水力平差模型,进行规划管网的水力计算,并根据计算结果对管网进行调整,得到满足规划供水量及水压要求的供水管网布置方案,为供水规划管网设计提供科学的依据。
Pipeline network design was an important part of the water supply planning. In order to reduce the leakage and operating cost, hydraulic calculation should be made during the water supply planning. Based on the characters of planning pipeline hydraulic calculation, the hydraulic model has been built by application of GIS and EPANET. With the model, the hydraulic calculation of planning pipeline network was completed and some of its adjustment was made. As consequence it provided the scientific basis for the water supply planning. As a case study, this approach was applied in water supply planning in the Shunyi District of Beijing.
