城市雨洪综合模拟方法及应用

为综合模拟城市雨洪和分析其对区域内涝的影响,在Open MI异构模型集成平台上动态耦合河网水文水动力模型和城市排水管网水力模型,以上海14个水利分片之一的淀北片为例,建立了淀北片雨洪耦合模型,并应用此模型分析了不同雨潮组合对淀北片区域内涝的影响。淀北片雨洪综合模拟计算结果表明,雨洪综合模拟较真实地反映了感潮河网城市地区的内涝情况,可为城市防洪除涝工作提供参考。

Method for integrated simulation of urban storm water flow and its application

In order to simulate urban storm water flow and analyze its influence on zonal waterlogging, a hydrological and hydrodynamic model for river networks and a hydraulic model for urban drainage networks were dynamically coupled using the OpenMI technology. Using the Dianbei zone, one of 14 water conservation zones in Shanghai, as an example, a coupled urban storm water model was established. Then, the effect of the combination of different types of rainstorms and tides on zonal waterlogging in the Dianbei zone was analyzed using the model. The results indicate that the model can precisely simulate urban zonal waterlogging in tidal river networks and provide reference for urban flood control.
