摘要
本文从建立自压半固定式喷灌系统的各级管道造价模型出发,探讨独立管网面积、形状对工程造价的影响,提出管网优化布置的顺序和方法;同时提出了不同地面比降与最佳管网面积关系的回归方程。
The authors have probed into the relation between the project cost and area and the shape of independent pipe network from setting up a cost model of different graded pipes for permanent gravity sprinkler system and put forward the sequence and method for optimization planning pipe network. At the same time, the authors have also presented a regression equation of the relation between different ground slopes and optimal pipe network area.
