基于 PCSWMM 的天津市空港经济区西南部暴雨内涝模型模拟

城市化建设的加快使得天津市内涝危害日益增大, 采用 PCSWM M 模型, 选取天津市空港经济区西南部建立暴雨内涝模型, 计算发生不同频率降雨时, 研究区域排水流量以及检查井溢流情况。结果表明, 随着降雨频率的减小( 降雨重现期的增大) , 空港经济区西南部分检查井溢流情况越来越严重。因此, 可通过计算出溢流点位置、 溢流点积水时间、 积水量等, 为相关管理部门解决排水防涝问题提供一定的参考依据。

Study on urban storm2flood simulation in Tianjin Southwest Airport Economic Zone based on PCSWMM

For the increasingly serious urban rainstorm waterlogging problems, based on PCSWM M model, select T ianjin Municipal Airport Eco2nomic Zone in the southwest region of rainstorm and flood model was established, calculated with different return of regional export flow and re2gional inspection wells overflow period under the condition of rainfall. T he results showed that, with the increase of rainfall reappearing period,regional water become more and more serious. T herefore, it can be calculated by calculating the position of the flood point, flooding duration,flooding volume, etc. Provide a reference for the relevant management departments in time to find and solve the storm 2flood problem.
