在分析芙蓉江流域暴雨洪水特性的基础上，采用多种方法插补展延了洪水资料系列，并充分利用历史洪水调查资料，使设计洪水分析计算采用的资料具有一定的代表性、可靠性。其中坝址百年一遇设计洪水洪峰流量为12000m3/s,72h洪量为10.2亿m3。对江口水电站设计洪水成果，通过与上下游、干支流各站的设计洪水参数及与长江流域的部分大中型水利水电工程设计洪水成果比较，进行了合理性分析。

On the basis of analyzing the characteristics of storm floods inFurong river basin, several methods are employed to interpolate and extend flood data,and investigation data of historical floods are fully used to make the data used for analysis and calculation of the design flood be more representative and reliable. The peak discharge of the design flood with a frequency of 100 years at the damsite is 12 000 m3/s, and the peak flood volume in 72 h is 1.02 billion m3.A reasonableness analysis of the calculated design flood for Jiangkou hydropower station is conducted by comparing the design flood with the corresponding discharges at upstream and downstream hydrologic stations on the main river and its tributary rivers,and with the determined design flood for some large and middle-sized projects in the Yangtze basin.
