S274.2; 出水口的位置不同,田间管网布置方案也不同,从而影响田间管网的投资费用,以往的研究大多忽略了出水口位置对管网投资的影响.[目的]探究在自压供水条件下,出水口位置对田间管网建设费用的影响.[方法]分别对出水口位于地块一角、地块一边、地块中间3种情形建立以毛管长度、支管管径为决策变量,以微喷灌田间管网总投资最小为目标的优化模型,采用变径设计,选用遗传算法求解.[结果]与传统规范设计方案相比,出水口位于地块一角、一边和中间的模型优化方案,管道投资分别降低了20.0％、9.5％、23.9％.对比规范设计结果,出水口位于地块一边的管网投资最小,比出水口位于地块一角的布置方案投资降低了13.4％,出水口位于地块中间比位于一角时布置方案投资降低了7.2％;对比模型优化结果,出水口位于地块中间...
