基于水力模型的城市供水主干管网联通工程研究

Drinking Water Distribution Main Network Interconnection Project Based on Hydraulic Model

以南方某城市供水主干管网互联互通保障工程为例,采用WaterCAD软件开展不同工况下供水管网水力模拟等工作,分析现状供水系统的供需风险,并基于模拟结果在全市集约化供水格局的背景下提出主干管网联通设计方案。结果表明,联通管设计充分发挥了集约化水厂群的规模效应,能有效解决未来社会发展造成的用水矛盾,提高供水安全保障能力,实现“多源并举、一网调度”。

WaterCAD software was used to carry out hydraulic simulation of a drinking water distribution network interconnection project in a southern city under different working conditions.In addition,the supply and demand risks of the current water supply system were analyzed,and the design scheme of the water distribution main network interconnection project was proposed based on the simulation results and the background of urban intensive water supply pattern.The design of the pipe interconnection fulfilled the scale effect of the intensive water plant group,which effectively solved the water contradiction caused by social development in the future,improved the capacity of water supply security,and realized“multi‑source simultaneous operation and one‑network distributing”.
