摘要
选取受同纬度带大气环流影响 ,天气系统发展产生降水所涉及的金沙江、雅砻江、大渡河、岷江、涪江、嘉陵江流域 ,研究美国推求可能最大降水的时—面—深概化法在我国西南地区的应用。研究以雅砻江为设计流域。成果已用于二滩水电站的设计洪水复核和官地水电站的设计洪水计算 。
By selecting river valleys Jinshajiang,Yalongjiang,Daduhe,Minjiang,Fujiang and Jialingjiang concerning precipitation in same latitude zone and same atmaspheric circulation weather system,the application of rain-storm duration-surface-depth generalized method for deducing probable maximum flood of United States in Southwestern region of China is studied.The research takes Yalongjiang as design valley.The result has been used in design flood check of Ertan Hydroelectric Plant and design flood calculation of Guandi Hydroelectric Plant.The result shows close approximation with other methods.
