扩建给水管网的直接优化计算方法

Directly Optimum Calculation Method of Enlarging Water Supply Pipe Net

根据扩建管网的特性 ,构造了直接以管段直径为求解变量的优化设计目标函数 ,利用约束条件的水力特点 ,采用了优化效果明显的广义简约梯度法 (GRG)进行计算 ,并通过目标函数变换 ,一次性解决了求解管径标准化的难题 .

In this paper,we constructed an optimun object design function of pipe cliameter according to character of enlarging pipe net.we used condition of restraint of water power character,adopted optimum general roughness gradient (GRG) Method to calculate,and changed the object function to solve the problem of pipe diameter standard.
