【摘要】 城市给水工程主要是由取水、水处理和管网系统三部分组成。其中，城市管网系统部分，主要是负责将洁净水输送到千家万户，以保证城市居民生活、生产的用水，是重要的市政设施，其费用可占整个给水工程总投资的50%～80%，并且，每年还要投入大量的资金用于其改建、扩建和维护。因此，了解城市管网的现状，及时获取其运行数据信息，对城市管网进行科学管理是十分必要的。 众所周知，当今社会是一个高速发展的社会，信息化大潮正席卷全球，信息化水平已成为衡量一个国家和地区现代化水平的重要标志。城市给水管网系统，是城市的命脉。它结构复杂、规模庞大、用水随机性强，是一个多目标的运行控制网络系统。要对其实现科学管理，首先必须对管网系统进行水力分析计算和模式的复核计算，以期获取准确的运行工况数据。在此基础上，可进行管网的改建、扩建工程的优化设计，并增强自来水公司对突发事件快捷反应能力，从而能避免工作上的盲目性。 多年来许多国内外专家致力于给水管网计算和分析方法的研究及其运用。随着70年代网络(图论)技术的发展，人们利用图论来构造给水管网的节点方程和环方程。简洁明了的矩阵描述的方式，使人们对繁杂的系统、方程本身的性质及其应用有了更直观、更深刻的了解，新的求解思路由于计算机技术的成熟得到了实现。“依靠信息技术改造传统的管理模式”已经受到大家的普遍认同，各种技术的交互使用，既推动了理论方面的研究，又使应用软件的开发得到了快速的发展。 本文在分析和研究最新给水管网计算原理的基础上，开发出一套管网计算分析应用程序，将GIS技术成功地运用到了管网系统管理中。论文分为三部分： 武汉理工大学硕士论文：给水管网水力计算方法与应用程序的开发研究 第一部分工作是进行理论分析，建立管网分析计算的数学模型， 并选择了适当的求解方法。 第H部分是运用 门S 技术，在 Visual Basic 开发环境下嵌入 Mapobject控件，进行管网计算分析应用软件的编制工作。 第三部分是以某市的地理信息资料为背景，模拟了城市给水管网 现系统，并应用该软件系统进行管网的分析计算和复核工作。 论文第一部分和第二部分工作是本论文的核心内容，重点介绍和 分析了目前比较适合在计算机上实现的管网分析计算方法，应用GIS 技术，开发的应用软件界面生动。第三部分是通过对给水管网的建模 和计算分析，证明了该程序图形界面简洁明了，运行计算效果良好， 用户操作方便简单，获取工况运行数据直观、准确、快捷。更多还原

【Abstract】 Water supply engineering mainly includes three parts. They are water taking, water processing and the network system management. The functions of the network systems, which are the important municipal facilities, are to lead the clean water to thousands of household and supplly water for the citizen life and productim. Its cost can occupy 50%~80% of invertmont on total water supply engineering. Annually it neetes a large quantity of money to construct and maintain. Therefore, to understand the current situation of the network system and to obtain the information of its working data in time are necessary for city management.As everyone knows, the present society is a fast developing society. The tide of informationalization rolls up the world. The level of informationalization has become an important marking to measure modernization of a nation and a region. The municipal water supply network system is the city’s life vein. It is a multi-target controlling work network system, with complicated construction , -tremendous scale and high randomness of water demand. To administrate the network system scientifically, it is necessary to do hydraulic analysis calculation and mode check calculation firstly and then to obtain the accurate working data in different cases. Based on this, the optimal design for reformation and extension of the network system can be carried out, and its fastness reaction ability to deal with sudden accident will increase.A great number of domestic and foreign experts have been studing studied on the calculation and analyses method for many years. Along with the development of network technique, the node equations and circuit equations were set up by using scheme method. The concept of " Depending on the information technique to reform traditional administration mode" has been widely accepted.Based on the researches and analyses of recent calculation principles of water supply network, this paper develops a program of network calculation and analyses. CIS technique has been successfully used in this case.This paper includes three parts:(1) Theory analysis.The mathematical model of the calculation for network is established and a appropriate solution is chosen.(2) With MapObject, a network analyses program in Visual Basic development environment is worked out.(3) Based on the geography information of a city, a water supply network is drawn and the network calculation and analyses is carried out.The first part and the second part are the core contents. The information resources share is the intention of nowadays city informationalization. Applying of this program will propel the procedure of scientific management of municipal networks.更多还原
