摘　　要：基于水动力数值模拟方法,采用MIKE11构建一维水动力模型,MIKE URBAN构建管道水流模型,MIKE FLOOD耦合一维水动力模型与管网水动力模型,建立适用于城市设计洪水模拟的耦合模型。选取深圳市宝安区沙井河片区为研究区域,推求典型断面设计洪水;将计算的各断面设计洪水与传统水文分析方法计算结果进行对比。从对比分析结果来看,应用水动力耦合数值计算方法计算的设计洪水结果较传统方法计算结果有所差别,符合区域城市化后洪水变化的一般规律。One-dimensional hydrodynamic model and pipeline flow model are established by MIKE11 and MIKE URBAN respectively,which is based on the hydrodynamic numerical simulation method;they are coupled by MIKE FLOOD also,with the coupling model suitable for urban design flood simulation established.The design flood calculated by selecting typical sections from research area in Shajinghe area,Bao an District,Shenzhen,and the calculated design flood of each section is compared with the calculation results by traditional hydrological analysis methods.The comparative analysis shows that the design flood results calculated by the hydrodynamic coupling numerical calculation method are different from those by the traditional method,but they conform to the general law of flood change after regional urbanization.
