Leakage analysis and leakage point positioning method for large-water-volume water delivery and supply pipe network

The invention provides a leakage analysis and leakage point positioning method for a large-water-volume water delivery and supply pipe network, which comprises the following steps of: firstly, carrying out area division on a main pipeline and a branch pipeline of the water delivery pipe network with the branch pipeline, and then integrating basic information of the pipe network and measuring segmented pressure and water volume of each area in real time; the actual water damage is combined with a Haizerwillii hydraulic calculation formula, and pipe network leakage point positioning is obtained through accurate calculation. The method has the beneficial effects that the method can be applied to planning and design of a large-water-volume water transfer and water delivery and supply pipe network, and leakage information and leakage point positioning information of the water supply pipe network are remotely monitored. 本发明提出了一种大水量输供水管网漏损分析和漏点定位方法，首先对有分支管路的输水管网进行主线管路和分支管路的区域划分，再综合管网基础信息和实时测量每个区域的分段压力和水量，利用实际水损结合海曾威
