摘要
本文研究了微灌系统优化设计中支、毛管允许压力水头偏差的分配问题。在平坦地上布置微灌系统时,得出了支、毛管的最优分配比例不是一个定值,而是随支管上毛管的根数、管道价格、支毛管长度而变。打破了国内一直沿用单一常数的认识,对节约管网投资有一定的实际意义。
Study on the allocation of permissble derviation of water pressure of submain and lateral in the optimization design of micro-irrigation system. When planning micro -irrigation system on level ground, The optimal allocation ratio changes with the number of lateral at submain, The unit price of pipe and the length of submain and lateral. It is not a constant. This conclusion breaks the knowledge of single constant used at home and has certain practical significance for saving the cost of network line.
