外部多水源给水管网水力计算程序的应用

基于求解管网恒定流方程组的Hardr-Cross法(哈代-克罗斯法)及其算法原理，研究管网图形网络结构与水力计算中数据结构的特征．引入虚节点和虚环，将外部多水源管网问题转化为单水源问题．结合某管罔规划设计，以环为主线的编程思路，用C语言编制相应的计算程序并通过调试．

Application of Programming to Hydraulic Computation for Water Supply Pipe Network with External Multiple Water Sources

By using Hardy-Cross method and its algorithm principle which are suitable for solving equations of steady flow in pipe network, a study is made on the graphical network structure of pipe network and the characteristic of data structure in hydraulic computation. By leading in virtual node and virtual loop, the problem of pipe network with external multiple water sources will be transformed into problem of single water source. Combining with the planning and the design of certain department concerned as well as the programming thinking with the loop as principle line, C-language is applied to compiling corresponding computer program and its debug has been passed.
