摘　　要：运用全局灵敏度分析方法(Sobol’法)对供水管网模型中的管道摩阻进行灵敏度分析,选取灵敏度较大的管道进行参数校核,并以实际给水管网为实例进行自动校核工作.校核结果表明,利用Sobol’法求得管道灵敏度后,只校核灵敏度较高的管段摩阻,减少了决策变量的个数,大大降低了校核时间,运用精英型非支配排序的多目标优化算法(NSGA-Ⅱ算法)进行求解,提高了校核效率,达到了预定的精度要求.Urban water supply network is of critical infrastructure. In the process of water distribution network planning, operation management and optimization scheduling, it needs to understand the hydraulic and water quality status of water distribution network comprehensively. The establishment of water distribution network hydraulic model is the most effective method. In this study, Sobel＇ sensitivity analysis method is selected to analyze the parameter sensitivity in the model, then a real water supply network is taken as an example for automatic calibration. The results show that with Sobol＇ sensitivity analysis method and NSGA- Ⅱalgorithm, calibrating the pipe friction factors which have higher sensitivity, can reduce the number of decision variables and calibrating time.
