【摘要】 本文在应用经典的管网优化方法——拉格朗日算法对给水管网进行优化计算的基础上，探索快速、准确设计给水管网的途径，寻找简化数据输入的方法，力求用更短时间做更高水平的管网设计。为此，在优化水力计算的同时也对数据进行优化设计，尽量做到前后数据的关联应用，建立起管网图形基本信息数据库。然后应用AUTOCAD二次开发工具Visual LISP编写出绘制管网系统图程序和绘制等水压线图程序，在AUTOCAD平台上将平差或优化的结果快速成图，从而完成从节点流量开始到管网优化直至绘出给水管网系统图和等水压线图的一整套设计。 算例实际应用表明，开发出的程序使用方便快捷，简化了给水管网优化设计工作，能大大提高给水管网优化设计的工作效率，并使优化的结果便于管理。程序绘出的环状管网系统图和等水压线图，不但直观易懂，不易出错，还为城市地理信息系统的有效管理提供了可靠的依据。更多还原

【Abstract】 Based on the application of the classic Lagrange algorithm on water supply networks optimization calculation, the way of designing water supply networks fleetly and accurately is investigated. In order to do better with shorter time during the water supply networks design, the way of simplifying the data input is looked for. At the same time of hydraulic calculation, the basic graphical information database is established by optimizing design the data for the connection application of the data. Then applying the second development tool of AUTOCAD, Visual LISP to scheme out the programs of plotting the network’s systems drawing and the water isobar. Consequently, the whole set design from the node outflow distributing to plotting the network’s systems drawing and the water isobar is completed.Actual applications express the usage of the procedure worked out is convenient and fast. The work efficiency can increase consumedly. And this makes the optimization result easy to manage. These drawings that plotted by the programs not only make the system information understand easily, but also make mistake not easily. These provided the dependable basis for the valid management of the city geography information system.更多还原
