摘　　要：为有效降低城市供水漏损率,快速、准确定位漏失位置,基于压力敏感区域方法,以A市为研究区域对供水管网漏失区域定位进行研究,以压力监测设备与节点漏失之间的水力关联特性对供水管网进行区域划分,建立管网漏失敏感区域,当某处发生漏失时,可立即定位到漏失区域。结果表明,当漏失响应阈值为97%时,覆盖节点数量最多,敏感区域划分最为准确,且漏失点离压力监测点仅200 m左右,定位效果明显。相较于常规的漏失检测方法,该方法能有效缩小检漏范围,提高检漏效率。In order to effectively reduce the leakage rate of urban water supply and locate the leakage location quickly and accurately,this paper studies the location of leakage in water supply network based on the method of pressure sensitive region.Based on the hydraulic correlation characteristic between pressure monitoring equipment and nodal leakage,the water supply network is divided into regions,and the leakage sensitive region is established.The results show that when the threshold value of leakage response is 97%,the number of covered nodes is the most,the sensitive region is divided the most accurately,and the leakage point is only about 200 m away from the pressure monitoring point.Compared with the conventional leak detection methods,this method can effectively reduce the leakage detection range and improve the leak detection efficiency.
