摘  要:
管道灌溉是常用的节水灌溉方式之一,在管道输水灌溉系统中,管网投资约占总投资的60%~70%,直接影响工程造价。因此加强对管网优化设计的研究,找出一种简单高效的优化方法,对提高管道输水灌溉工程设计水平,降低运行费用具有重要意义。在现有管网优化设计模型的基础上,以管网年费用最小为目标,建立了管道输水灌溉管网优化设计模型,并采用界限流量法求解,推导出了相邻管径的界限流量的计算公式。

摘  要:
Pipe irrigation is one of the common-used irrigation methods.In the pipe-irrigation system,the proportion of the pipe investment takes 60%-70%,which directly affects the project cost.Therefore,it's significant to obtain an easy and highly efficient optimal design,in order to enhance the design level of the pipe-irrigation.Based on the current pipe optimal design model,taking the minimum annual cost of pipes as the goal,the optimal design model of pipe-irrigation was set up.The solution was processed by using flow bounds approach.And the computational formula of the flow bounds of the adjacent pipe diameter was deduced.
