摘要
本文提出一种高效的树状管网系统水力分析的有限元法，求解水泵、管道、管件、灌水器组成的整体工况，使具有６４０Ｋ内存的ＰＣ计算机能求解具有三级管网、节点多达６０００的系统水力计算问题．可供设计、运行管理与仿真应用．
This paper presents a high efficiency finite element method for tree-shape network hydraulic computation to determine the,operating duties of pumps, pipes,fittings and emitters.It makes the posibility of using a PC computer with a 640 k bite RAM to solve a stiffness matrix of 6,000 node which has main, submain and lateral piping network.A computer program has been developed which can be used for the purposes of design,management and simulation of a pressure irrigation sysstem by existing small computer.
