摘要
三水、马口站是西北江三角洲上游主要的水文控制站,为防洪报汛及区域水利工程建设的需要,根据三水、马口站实测水文资料计算两站百年一遇设计洪水。该文通过资料收集、数据插补、系列代表性分析、历史洪水调查考证确定设计洪水计算的数据系列,采用频率分析计算、典型洪水的选取、计算设计洪水放大倍比等方法确定两站设计洪水过程线。通过合理性分析,认为频率分析和设计洪水成果误差满足要求,结果合理可靠,对相关研究设计具有实际参考价值。
According to the measured hydrological data of Sanshui and Ma Kou,the design flood of the two stations in a hundred years is calculated. The calculation process of design flood is discussed in detail from the aspects of data collection,series representative analysis,historical flood investigation,frequency analysis and calculation,selection of typical flood and rationality of the results. Sanshui and Makou are located at the top of the Northwest River Delta. The design flood of the two stations provides data support for the construction of regional water conservancy projects and flood control optimal operation.
