摘要
针对武汉市海绵城市试点建设,在青山海绵示范区内构建了基于Info Works ICM的排水管网模型。利用Info Works ICM通过一维模拟实现排水系统的排水能力评估,通过二维模拟实现内涝风险评估。模型模拟得出,武汉市青山海绵示范区仅46.3 km、约15.2%的排水管涵可以满足3年一遇降雨重现期的设计要求,排涝泵站尚不足以满足3年一遇降雨重现期的设计要求;示范区内涝高风险区和中风险区面积分别占示范区面积的2.7%和1.5%。
For the pilot construction of Wuhan sponge city, the drainage network model was con- structed in Qingshan sponge demonstration area based on InfoWorks ICM software. 1D simulation and 2D simulation were conducted by using InfoWorks ICM to achieve drainage capacity assessment and waterlog- ging risk assessment, respectively. Within the Qingshan sponge demonstration area, the length of drain- age sewer that can meet the design requirement for 3-year return period was only 46.3 km, accounted for 15.2%, and the drainage capacity of pumping station cannot meet the design requirement for 3-year re- turn period. Furthermore, waterlogging high-risk zone and middle-risk zone accounted for 2.7% and 1.5% , respectively.
