【摘要】 随着城市化的发展,城市的洪水灾害在国家和地区的历年灾害损失中所占的比重越来越大。要从根本上解决城市洪涝灾害,还有大量工作要做,其中最关键问题是必须深入研究城市地区水文变化规律和城市发展对水文特性的影响过程,这样才能合理和有效地进行排水工程规划设计与决策管理。 本文针对目前的研究状况和需要,结合上海市城区产流及排水特点,研制出较为适合我国城市化影响地区通用的雨洪数学模型,并通过与地理信息系统结合,开发了一个操作简单、形象直观的可视界面。模型针对实时和规划条件,动态模拟区域内各排水片和街区的地面积水过程,满足了市区防汛预报、水情分析、工程规划与决策管理等工作的要求。 根据历史上已发生的特大暴雨过程的实际调查结果表明,模型模拟的结果是良好的。更多还原

【Abstract】 With the development of urbanization, the proportion of flood calamity of city is heavier and heavier in losing over the years in countries and regions. In order to solve the urban flood problem fundamentally, there is a large amount of work to be done. Among them the most key problem is to further investigate the hydrology changing regulation in the urban areas and impact on hydrology characteristic for city’s development. It could be rational and effectively to make policy and manage, to plan and design drainage system in this way.According to the present research states and needs, a rainfall runoff model suitable for city flood simulation is established for Shanghai based on the characteristics of producing runoff and drainage, and a visual interface using GIS which can be easily operated is developed. In both real time and planning situations, this model can be used to dynamically simulate the whole flooding process of all city blocks. It satisfies the needs of flood forecast, flow condition analysis, engineering planning and management, and making policy and management of the city.According to the actual investigation result of the course of extra torrential rain that had happened in history, the result of model simulation is good.更多还原
