摘　　要：山地丘陵地区的城市供水管网,在满足用户用水需求的同时,可能面临局部区域压力过高的问题,而高压会导致供水管网的漏损量增加。依托某山地城市供水管网水力模型,提出“界限清晰、压力均衡、水头递减、局部加压”的分区分压策略,对供水管网进行压力分区划分,配合基于时间的阀后压力控制方式进行分区控压,相比于传统的阀后压力控制方式,能够更好地减少管网漏失水量,均衡管网压力,为山地城市供水系统的运行提供了重要参考。Leakage in urban water supply pipeline networks results in significant waste of water resources,and the rational regulation of water supply pipeline network pressure is an effective means of leak management.In mountainous and hilly urban areas,the water supply pipeline network may face the challenge of excessively high pressure in local regions,leading to increased leakage.Leveraging the hydraulic model of a specific mountainous urban water supply pipeline network,this study proposes a pressure zoning strategy characterized by“clear boundaries,pressure balance,head decrease,and local pressurization.”The strategy involves dividing the water supply pipeline network into pressure zones and implementing zone-specific pressure control using a time-based valve-after-pressure control method.Compared to traditional fixed valve-after-pressure control methods,this approach proves more effective in reducing water losses in the pipeline network,balancing network pressure,and providing essential guidance for the operation of water supply systems in mountainous urban areas.
