【摘要】：水与人类生活、生产息息相关,供水管网是城市建设中最重要的基础性设施。供水功能的优劣决定着城市未来的发展。然而随着城市规模的扩大,旧城区供水管网老化,供水系统越来越大,越来越复杂,给供水企业管理带来很多困难。管网漏损一直是供水企业难以解决的问题,特别是漏损中的爆管问题,事先不容易预测,一旦发生爆管事故不但造成水资源的浪费,而且会极大影响人们的正常生活、生产作业。供水企业的目标正是保证自来水水质优良、水量足够的输送至用户。目前,国内对供水管网的研究主要集中在测压点优化布置、管网信息管理、漏损爆管原因、检漏措施及爆管后的事故处理,而对于爆管机理、爆管临界状态、管道安全评价、爆管预警系统的研究很少。本文旨在通过对供水管网历史爆管事故统计资料的分析,从中发现供水管网爆管事故内在规律,建立供水管网水利模型,根据测压点反馈的压力信息模拟管网实时运行状况,寻找供水管网的安全评价方法,从而得到供水管网的安全评价结果,之后将供水管网安全评价结果通过CAD平台直观显示,以颜色区分供水管网的安全程度。方便供水企业管理人员对供水管网维护、更换管道以及采取紧急措施。具体做法为：(1)对造成供水管网爆管事故的原因(静态因素、动态因素)进行分析,分析爆管机理,总结爆管规律；(2)本次研究引进模糊数学对供水管网进行安全评价,对各单因子分别赋予分值,采用因子权重法确定各因子占爆管因素的比例。(3)根据供水管网压力监测点反馈的压力信息,采用批次平差原理,建立管网水利模型,模拟管网实时运行状况,并通过测压点压力对供水管网模型精度进行校核。(4)可视化研究：采用VB程序语言对CAD二次开发,将供水管网安全评价结果导入CAD平台并显示。
[Abstract]:Water is closely related to human life and production. Water supply network is the most important basic facility in urban construction. The function of water supply determines the future development of the city. However, with the expansion of the city scale and the aging of the old urban water supply network, the water supply system is becoming larger and more complex, which brings a lot of difficulties to the management of water supply enterprises. Pipe network leakage has always been a difficult problem for water supply enterprises to solve, especially the pipe burst in leakage. It is not easy to predict in advance. Once a pipe burst accident occurs, it will not only cause waste of water resources, but also greatly affect people's normal life. Production operation. The goal of water supply enterprises is to ensure that the tap water quality is good enough to be transported to users. At present, the domestic research on water supply network mainly focuses on the optimal arrangement of pressure measuring points, pipe network information management, the causes of leakage and burst, leak detection measures and the treatment of accidents after the pipe burst. However, for the mechanism of pipe burst, the critical state of pipe burst, the safety evaluation of pipeline, There is little research on early warning system of tube burst. The purpose of this paper is to find out the inherent law of pipe burst accident in water supply network by analyzing the statistical data of pipe burst accident in history of water supply network, to establish water conservancy model of water supply network, and to simulate the real-time operation of pipe network according to pressure information feedback from pressure measuring point. The safety evaluation method of water supply network is found, and the safety evaluation result of water supply network is obtained. After that, the safety evaluation result of water supply network is displayed intuitively through CAD platform, and the safety degree of water supply network is distinguished by color. It is convenient for water supply management to maintain, replace and take emergency measures on water supply network. The specific measures are as follows: (1) the causes (static factor, dynamic factor) of pipe burst accident in water supply network are analyzed, the mechanism of pipe burst is analyzed, and the rule of pipe burst is summarized; (2) the safety evaluation of water supply network is carried out by introducing fuzzy mathematics. The factor weight method is used to determine the proportion of each factor to the pipe burst factor. (3) according to the pressure information feedback from the pressure monitoring point of the water supply network, the water conservancy model of the pipe network is established by adopting the principle of batch adjustment. The real-time operation of the water supply network is simulated, and the accuracy of the water supply network model is checked by pressure measurement. (4) Visual research: the second development of CAD is carried out by using VB program language, and the safety evaluation results of the water supply network are imported into the CAD platform and displayed.
