摘　　要：针对给水管网模型建立过程中存在的偏差问题,通过收集管网运行中的实测数据及对管道合理分组,建立了给水管网的校核模型,运用遗传算法对不同管材、管径及铺设年代的管道的摩阻系数进行了校核。计算结果表明,该模型的模拟值与实测值基本吻合,可以达到预定的精度要求。Aimed at the issues of deviation.in the establishment of water supply network model, a verification model for water supply network was established by collecting the actual detection data of the network operation and reasonable grouping for the pipelines. The friction resistance coefficients of pipelines with different materials, diameters, layed time were verified using genetic algorithm. Calculation results indicated that the simulated values were very close to the measured values, and it could satisfy the requirements of preset accuracy.
