摘要：

To　solve　the　recurrent　flooding　of　concave-down　overpass　bridges　and　the　problem　that　storm　water　management　model　(SWMM)　cannot　simulate　the　water　diffusion　on　the　surface,　a　method　of　urban　flooding　simulation　on　concave-down　overpass　bridge　by　developing　SWMM　was　presented　in　this　paper.　The　method　built　high　precision　DEM　of　overpass　bridge　and　obtained　the　topography　of　bridge.　Then,　the　way　of　junction　flooding　that　was　modeled　by　SWMM　was　developed.　It　made　the　floods　flow　upon　the　topography　of　bridge.　The　method　solved　the　problem　that　the　junction　flooding　does　not　diffuse　on　the　surface　in　traditional　simulation.　The　modeling　of　urban　flooding　process　on　concave-down　overpass　bridge　was　realized.　Results　show　that　this　method　provides　the　support　for　the　prevention　and　treatment　of　urban　flooding　on　overpass　bridges.　©　2016,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
