摘　　要：为了明确叠压供水方式的准入标准,提出了用于叠压供水设备选取及城市给水管网压力变幅分区的判据,并对其重要参数——叠压最小允许压力H_(dmin)、叠压最大压力波动ΔH_(dmax)进行原理分析,据此判据将城市给水管网划分为压力稳健区、压力波动区、压力脆弱区,并以在西部A市自来水公司GIS、SCADA系统采集的2022年西部A市主城区年最大用水日时全部供水节点的日最大水压、最小水压为可信数据,作出西部A市主城区给水管网的压力变幅分区图,以此作为西部A市主城区叠压供水设备选取的参考依据。The criteria for selection of superimposed water supply equipment and zoning of pressure variation in municipal water supply network were presented.The principle analysis of its important parameters,such as minimum allowable pressure H_(dmin) and maximum pressure fluctuationΔH_(dmax),were carried out.According to this criterion,the municipal water supply network can be divided into three zones:stable pressure zone,fluctuating pressure zone and fragile pressure zone.Finally,the maximum water use day of the main urban area of west A city in 2022 collected in the GIS and SCADA system of west A city,the maximum water pressure and minimum water pressure of all water supply nodes on the same day were taken as credible data,and the pressure variation zoning map of the water supply network in the main urban area of A city in the west was drawn,which is taken as the reference basis for the selection of pressure superimposed water supply equipment in the main urban area of A city in the west.
