摘　　要：九湾潭水库是广州市流溪河流域内一座中型水库,研究其设计洪水对广州市防洪工作具有重要意义。设计洪水是保证水库工程安全的一个重要设计依据,也是水库防洪调度的基础。采用综合单位线法和推理公式法,进行九湾潭水库的设计洪水推求计算以及设计暴雨参数选取研究。结果表明,采用综合单位线法计算出的设计洪水更符合防洪要求,又用该方法推求出不同频率下九湾潭水库的设计洪水,为九湾潭水库在以后进行防洪调度提供了依据。Jiuwantan Reservoir is a medium-sized reservoir in Liuxi River basin of Guangzhou City.It is of great significance to study its design flood for flood control in Guangzhou City.Design Flood is an important design basis to ensure the safety of reservoir engineering,and is also the foundation of reservoir flood control operation.In this paper,the integrated unit line method and the inference formula method were used to calculate the design flood and select the parameters of design storm in Jiuwantan Reservoir.The results show that the design flood calculated by the integrated unit line method is more suitable for flood control,and the design flood of Jiuwantan Reservoir with different frequencies were calculated by the method,which can provide a basis for flood control operation of Jiuwantan Reservoir in the future.
