摘　　要：针对给水管网系统所面临的改扩建问题 ,建立了给水管网系统实用优化改扩建模型。采用遗传算法求解 ,一次性解决了求解管径标准化的难题 ,同时计算得到水源最优分配流量。在不影响水力模型计算精度的前提下 ,引入管网简化 ,对非改扩建区域的管网实现任意程度的简化 ,大大提高了计算速度 。A genetic algorithm based practical mathematical model was developed for optimizing reconstruction of water distribution network. This model solves the problems on standardization of pipeline diameter and the best distribution of water sources one-step. In order to improve the calculation speed, a simplified water distribution network was introduced with the precondition of acceptable calculation precision. These approaches have been proved with an actual water distribution system.
