摘要
针对沿海城市特大暴雨及其引发的城市内涝问题,以福州市为例,构建了基于Infoworks ICM的城市一维排水管网和二维陆面水动力精细化耦合模型,并将该模型应用于福州市古田路片区2021年8月“卢碧”台风暴雨内涝分析,验证了模型模拟精度较高,进而基于此模型,分析了不同重现期下古田片区暴雨内涝过程,提出了两种“海绵化”改造方案并模拟其对研究区暴雨内涝的缓解效果,发现增大管径更有利于改善研究区内涝现状。研究成果可用于准确计算福州市城区地下排水和陆面积水过程,为沿海城市防洪排涝实时决策提供技术支撑。
Aiming at the problem of urban waterlogging caused by heavy rainstorms in coastal cities,this paper takes Fuzhou City as an example and constructs a fined coupling model of urban one-dimensional drainage network and two-di-mensional land surface hydrodynamics based on Infoworks ICM.The model was applied to the analysis of rainstorm wa-terlogging in Gutian Road area of Fuzhou during Typhoon"Lubi"in August 2021,which verified the high simulation ac-curacy of the model.Based on this model,the rainstorm waterlogging process in Gutian area under different recurrence periods was analyzed,and two"sponge"reconstruction schemes were proposed.It is found that increasing the pipe diam-eter is more conducive to improving the waterlogging situation in the study area.The study can be used to accurately cal-culate the process of urban underground drainage and land area water in Fuzhou City,which provide technical support for the real-time decision of flood control and drainage in coastal cities.
