重力输水管渠系统优化

The Optimalization of Water Transfer Pipe and Canal in Gravity Water Supply System

在重力输水系统的规划设计中，有时采用无压管渠与压力管道相结合的方式输水。针对这种输水系统的特点，本文以整个重力输水管渠系统投资最小为目标函数，以无压管渠长度和压力管道中备选管道长度作为优化变量，建立了重力输水管渠系统优化设计的线性规划模型。

In the planning and design of gravity water transfer system, the combined pattern of pressure free pipe and canal with pressured pipe line is sometimes adopted to carry out water transfer. Aiming at the features of this water transfer system, a linear programming model is established with the smallest investment into the pipe and canal in gravity water transfer system as the objective function and with the length of pressure free pipe and canal and the length of pipes to be selected in the pressured pipe line as the optimal variables in this paper.
