摘　　要：水库上游伏流区溶蚀沟槽洼地较多时,可选择采用水库同一流域内的水文站洪水资料进行水库坝址处洪水计算,一般方法为水文比拟法,同时应结合历史洪水调查成果,采用雨洪法、伏流区洪水计算经验公式计算洪水后进行对比分析,并从偏安全等方面合理推荐采用的设计洪水计算方法及成果。When there are more erosion depressions in hyporrheic zone in upstream of a reservoir,the flood data collected from the hydrological station which is located at the same basin with the reservoir can be used to carry out flood calculation at dam site of the reservoir.General method is hydrological analogy,meanwhile also should be combined with investigation results of historical flood,and rain flood method as well as empirical formulas for flood calculation should be used to calculate the flood,then be carried out comparing and analyzing,at last calculation method and results for design flood to be used should be recommended reasonably in term of partial safety.
