摘　　要：本文针对地表漫流与管流耦合对不同降雨重现期下内涝模拟的影响机理进行了重点研究。文中以长春市某管网片区为研究对象建立了InfoWorks ICM一维和二维模型,并对其进行了校验,进而分析了一二维水量动态交互对于城市内涝形成过程的影响。研究成果表明,耦合模型能够更加精准地刻画汇水区的实际水文特征,以及地表径流与地下排水网络间的动态交互关系,研究成果对于寒冷地区的内涝防治具有一定的指导意义。Aiming at the coupling of surface flood and pipe flow,this paper focuses on the mechanism of waterlogging simulation under different rainfall recurrence periods.Taking a pipe network area in Changchun city as the research object,this paper established the InfoWorks ICM 1-D and 2-D model,and verified it,and then analyzed the influence of 1-D and 2-D water dynamic interaction on the formation process of urban waterlogging.The research results show that the coupled model can more accurately depict the actual hydrological characteristics of catchment areas and the dynamic interaction between surface runoff and underground drainage network,and the research results have certain guiding significance for the prevention and control of waterlogging in cold areas.
