摘　　要：管网水力模型的校验是保证模型准确应用最重要的工作.大型供水系统管道多且错综复杂,管网中的问题机率较大,且排查困难.模型校验是梳理管网中非正常工况的重要时机.本文描述在Z市水力模型校验过程中,对重要输水管段存在的问题进行排查及解决的过程.通过模型模拟压力、流量数据和实际数据对比分析,定位问题区域,并采取区域压力测试和进一步的水力模拟,逐步缩小问题范围,最终找到管网中阻力存在的管段.管段阻力消除后,对提升后续管网压力有良好效果.Hydraulic model checking is the most important work before model applied.Due to the large pipe of water supply pipe is more,and complicated,so network problems in probability is bigger,and it is difficult to troubleshoot.Model checking is an important time combing network china-africa normal working condition.Article described in Z city in the process of model checking,the important water pipe sections screen and solve the problems existing in the process.This process is mainly by the regional stress test data analysis and hydraulic model simulation,gradually narrowing the scope of the problem,the resistance of the pipe section of pipeline network is finally found.To improve the follow-up after section resistance have been eliminated pipe network pressure has a good effect.
