摘　　要：本文基于压力管道水力学基本理论,针对长距离多泵站、多水源地供水联合运行问题,建立供水工程管网系统恒定流水力仿真模型,分别求解日常运行、常规检修与应急抢险等不同工况下管网系统中各点的压力与流量变化情况,从而检验系统的运行情况。结果表明,各工况下该供水系统压力极值都符合管道的承压标准,具备安全过流条件,可为类似供水工程的运行提供一定的参考作用。Based on the basic theory of pressure pipeline hydraulics,aiming at the joint operation of long-distance multi-pumping stations and multi-water sources,this paper establishes a simulation model of constant flow force of water supply engineering pipe network system,respectively solving the changes of pressure and flow at various points in the pipe network system under different working conditions such as daily operation,routine maintenance and emergency rescue,so as to verify the operation of the system.The results show that the extreme pressure of the water supply system meets the pressure standard of the pipeline under each working condition,and has the conditions of safe overflow,which can provide a certain reference for the operation of similar water supply projects.
