摘　　要：论述了遗传算法在城市给水管网优化应用中的原理和特点,针对传统遗传算法存在的问题 提出了改进意见,同时还介绍了改进遗传算法在四川某市给水管网改扩建工程中的应用情况。该计算 方法比传统的计算方法节省管道投资,而且因城市给水管网得到优化,水厂二泵站的电耗也得以降低。It is described the principles and characteristics of the application of genetic algorithms in the optimization of urban water networks. In view of the existing problems of the conventional genetic algorithm, it is presented suggestions for improvement and describes the performance of the improved genetic algorithm in the water networks upgrading and expansion engineering in a city. Compared with the conventional solution, the new method with optimization of the water networks that applies the improved genetic algorithm can save network cost. Power consumption is decreased in the secondary pumping station because of the optimization of the water networks.
