渠灌区管网输水系统优化设计问题研究

摘要

Based on the analysis of farmland pipe-irrigation system, two methods for optimalrndesign of farmland pipe-irrigation system are proposed. One is based on the single objectivernoptimal method for pipe diameter design applied in municipal water supply network and anotherrnis based on the multi-objective optimal method. A case study shows that these methods arernapplicable in engineering practice.%本文通过对农田灌溉管道输水系统的分析，提出了两种管道输水系统辅助优化设计方法，一是借鉴城市给水系统的rn单目标下管网系统管径优化计算方法，另一个是基于不完全偏好信息的农田管网系统多目标化设计方法，通过一个实际案例rn的应用表明：本文所提出的方法具有一定的实用性.
