摘要
本文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,并通过了实例验证。
Abstract: The diameters of each segment of pipeline are taken directly as the objective function of solving variables for optimum design according to the characteristic and structure of the expanded water distribution network. The calculation will be conducted by generalized reduction gradient (GRG) method with evident optimization effect under the characteristics of the restrict conditions and the difficult problems of standardization of calculated diameter of pipe have been solved once by the transition of object function.
