摘　　要：郑州市位于山前平原地带,受气候和地形条件影响,历史上极端暴雨频发,洪涝灾害十分严重,是国家防办公布的31个重点防洪城市之一。针对郑州市区开展洪涝分析,是服务郑州市防洪排涝,保障郑州市经济社会全面、协调、可持续发展的需要。采用MIKE系列模型,考虑复杂构筑物和内河水系河网的影响,在城市降雨产流模拟、大区域汇流及洪水演进模拟、城市地下管网排水模拟等关键技术研究的基础上,构建郑州市洪涝模拟模型,并利用2011年、2015年和2021年实测暴雨洪水资料进行了模型率定和验证。结果表明:模型模拟效果较好,计算结果与实测结果相差不大,可用于郑州市洪涝模拟评估。Affected by climate and topographic conditions,Zhengzhou has experienced frequent extreme rainstorms and serious flood disasters in history.It is one of the 31 key flood control cities announced by the National Flood Prevention Office.MIKE series models were adopted to construct a flood simulation model for Zhengzhou based on key technical issues such as simulation of urban rainfall and flow generation,simu-lation of large regional confluence and flood evolution,and simulation of urban underground pipe network drainage,by considering the influ-ence of complex structures and river network of inland river system.The model was calibrated and validated using the measured rainstorm and flood data in 2011,2015 and 2021.The results show that the model simulation effect is good,and the calculated results are not much differ-ent from the actual measurement,which can be used for flood simulation evaluation in Zhengzhou.
