摘要
对于管网优化及投资分析来说,最不利情况下的水力条件不是普遍条件,不能够完全代表管网应当有的优化假定条件。通过管道控制灌溉面积来确定管道的流量,按照满足在一天内,管道控制的所有灌水器都灌溉一次的原则确定,并给出公式。让管道的流量这一重要参数,在高效节水灌溉工程优化和设计计算中变得简单并容易计算。
For the analysis of pipeline network optimization and cost accounting,the worst hydraulic conditions is not a general condition,can not fully represent the assumed compatible conditions for optimization.The pipeline flow can be determined according to its controlling irrigation area under the principle that all the irrigation emitters controlled by the pipeline work one time once a day.The formula for this is given,too.So the study results make it easy to determine the pipe flow,which is an important parameter for the optimization and design of efficient water-saving irrigation projects.
