摘　　要：以某市YLQ水厂原水管道改造方案为例,探讨了水力模型在城市供水管网规划设计中的应用。根据实际情况提出了两种改造方案,并对改造后管道的送水能力、供水管网压力变化等进行模拟分析,进而模拟计算管道流速、水厂能耗及投资等情况。结果表明,若采用方案一进行改造,可以满足用水需求和供水管网的压力要求;若采用方案二进行改造,供水量略小于现状需水量,但可以满足供水管网的压力要求,并且会给供水企业带来更多的经济效益。Taking the reconstruction scheme of raw water pipeline of YLQ Waterworks as an example, the application of hydraulic model in planning and design of the urban water distribution system was discussed. Two reconstruction schemes were proposed according to the practical situation. The water delivery capacity of the reconstructed pipeline and the pressure changes of water distribution system were simulated and analyzed, and then the pipeline flow velocity, energy consumption and investment of the waterworks were simulated and calculated. The results showed that adopting the reconstruction scheme one could meet the water demand and the pressure requirement of water distribution system. However, adopting the reconstruction scheme two could not only meet the pressure requirement of water distribution system but also bring significant economic benefit to water supply enterprises except that the water supply was slightly less than the current water demand.
