摘　　要：以位于滞洪区的地下式水质净化厂为例,基于Infoworks ICM构建流域一维模型和滞洪区二维模型并开展耦合,通过实测暴雨数据和分洪过程进行率定和复盘,保证了模型可靠性。在此基础上,对滞洪区和水质净化厂防洪风险进行分析。结果表明:在现状防洪标准下,厂区存在防洪风险,其中降雨、控泄、河道构筑物及滞洪区糙率等因素也会不同程度影响水位变化,研究成果为滞洪区及水质净化厂后续的运营和应急管理提供科学的技术支撑。Taking the underground waste water treatment plant(WWTP)located in the flood detention area as an example,based on Infoworks ICM,a one-dimensional hydraulic model of watershed and a two-dimensional model of the flood detention area are constructed and coupled.The calibration and verification are carried out through measured rainstorm data and flood diversion process to ensure the reliability of the model.On this basis,the flood control risk of flood detention area and WWTP is analyzed.The results show that under the current flood control standard,there is a flood risk in the plant area.Rainfall,controlled discharge,river structures and roughness in flood detention area will affect water level changes to varying degrees,providing scientific and technical support for the subsequent operation and emergency management of flood detention area and the WWTP.
