摘　　要：为满足南水北调中线工程典型交叉河流防洪管理需求,确保中线工程防洪安全,构建索河交叉河流数据底板,以及洪水预报、洪水演进、风险分析等模型,结合2022和2023年汛期典型降雨洪水对模型参数进行率定,基于2021年郑州“7·20”暴雨对现状索河交叉河流进行预演分析,结果表明索河渡槽槽身存在阻水风险,中线工程安全风险较大。通过对防洪“四预”应用深入研究,实现南水北调中线工程交叉河流降水—产流—汇流—演进的全过程模拟,研究成果可进一步提升南水北调中线工程防灾减灾能力,为沿线交叉河流防洪应用提供参考。To meet the flood control management needs of typical cross-rivers in the Middle Route of South-to-North Water Diversion Project and ensure flood safety,this study developed a data foundation for Suo River crossing,along with models for flood forecasting,flood evolution,and risk analysis.Using calibration from typical rainfall and flood events during the 2022 and 2023 flood seasons,and based on the analysis of the 2021“7·20”heavy rainfall event in Zhengzhou,a predictive simulation was conducted for Suo River crossing.Results indicate a risk of water obstruction in the aqueduct body of Suo River,posing significant safety concerns for the Middle Route Project.Through in-depth research on the“Four Preventions”application in flood control,the full process of precipitation-runoff-confluenceevolution in cross-rivers of the Middle Route was simulated.These research findings contribute to enhancing the disaster prevention and mitigation capacity of the Middle Route Project,providing valuable reference for flood control applications in cross-rivers along the route.
