| 摘 要： | 从管网模拟仿真的微观和宏观模型入手，详细分析管网在正常及故障状态下的微观特性，在此基础上首次提出了管网故障局部停水后压力预测宏观数学模型，利用管网平差结果数据为宏观模型的拟合提供样本，采用“多元线性回归”方法进行拟合、分析，并检验了宏观模型的显著性及拟合精确度。编制了一系列计算程序，对管网进行实例计算和分析，结果令人满意。 |

| Abstract: | In the paper,microscopic characters of networks under normal state,and failure state conditions were analyzed through the networks microscopic and macroscopic models simulation.Based on the analysis,a macroscopic model for pressure prediction after regional water stoppage because of network failure was put forward firstly.Results of the network hydraulic analysis were used as samples to the regression of the macroscopic model,the model was fitted and analyzed by using the method multivariate linear regression,and the significance and fitting accurary were tested.A set of calculation programs were developed for this study,some real network examples were calculated and analyzed,and their results were satisfied. |
| Keywords: | Water stoppage for network failure Microscopic model Macroscopic model Pressure prediction. |
