Abstract
The control water conveyance trunk line of Longjiang River Valley Irrigation Zone Project is composed of a main trunk line and a south trunk line connected in series.The water conveyance distance is long,so the friction losses of pipeline are high.Rational selection of pipe diameter is necessary to achieve a reasonable balance between engineering benefits and investment.From two aspects of hydraulic calculation and pipe diameter selection,eco-nomic comparison and selection of hydraulic design schemes was conducted for the control water conveyance trunk line,so as to ensure the selected water conveyance scheme is economically reasonable and feasible,and provide a new perspective for the scheme comparison and selection of irrigation zone projects or long-distance water convey-ance projects in the future.关键词
