摘要
摘要:由于气候变化及城镇化进程加快，城市内涝问题愈加严峻. 为优化城市排水管理，有效减少内涝损失，以河北邯郸主城东区局部为研究区，计算了区域典型设计雨型，利用MIKE URBAN模型，模拟并判定了区域不同降雨情景下区域内涝分布情况，解析区域易涝点，进而模拟评估了不同管径排水管网负荷情况. 结果表明：随着重现期增加，区域检查井溢流的数量、区域最长积水时间以及最大积水深度都有所增加，区域管网超负荷面积增大；并且在10 、20 a重现期暴雨情景下，单纯扩增管径起到的径流缓解作用较少. 研究结果可为极端暴雨下区域洪涝预警部署以及城市排水系统改造提供技术支撑.

Abstract:Urban waterlogging has recently emerged more frequently and seriously due to climate change and accelerated urbanization. Regional rain process in the eastern urban district in Handan, Hebei, in different return periods was designed and calculated, waterlogging distributions in different scenarios were simulated and estimated through MIKE URBAN model, to decrease storm loss and optimize urban drainage management. It was found that with increase of return period, overflow points, waterlogging duration and maximum waterlogging depth all increased, resulting in the increase of overload drainage pipes. If only the pipes were simply expanded, the corresponding runoff reduction effect was negligible in ten-year and twenty-year storm event. This work provides some technical support for early warning deployment of stormwater and transformation of drainage pipeline networks.
