【摘要】 根据国家对排水防涝专项规划编制的要求,武汉市首次运用丹麦DHI MIKE软件模拟天津路、港西、黄孝河低排三个典型雨水系统的运行情况,针对模型建立、运行过程中管网和汇水面积的概化、参数的设置、降雨数据的选取、地形的设置、模块耦合等问题提出了注意要点。模拟结果与实际渍水情况相吻合,证明该模型是城市雨水系统评估的有效工具,可为雨水系统的标准制定、规划、管理、决策等提供强有力的技术支撑。更多还原

【Abstract】 According to the requirements of the drainage and flooding planning,the Danish DHI MIKE software was first used to simulate three typical stormwater systems for Wuhan City,including Tianjin road system,Gangxi system and Huangxiao river low drainage system.Matters needing attention in modeling,network and catchment generalization,parameter setting,rainfall data selection,topographic settings,module coupling and so on were proposed.The simulation results were consistent with the actual waterlogging situation.So this model is one of the effective tools to evaluate the city stormwater system,and provides a strong technical support for the stormwater system standard,planning,management and decision making.更多还原
