摘　　要：根据某水库流域1996-2020年各水文站以及雨量点降雨量的逐日资料和相关的洪水资料,对水库流域暴雨特性和洪水形成的特点进行统计分析,探求该流域暴雨和洪水形成的普遍规律。统计调查结果显示,某水库流域夏季洪水与暴雨的对应关系明显,秋季则不显著。同时利用水文比拟法、《XX省暴雨径流查算图表》及XX省新等值线查算法,对水库坝址处洪水进行分析计算,计算出洪水的数据,为水库坝址的洪水设计提供了可靠的参考数据。According to the daily data of precipitation and related flood data of each hydrological station and rainfall point in a reservoir watershed from 1996 to 2020,this paper makes a statistical analysis on the characteristics of rainstorm and flood formation in the reservoir watershed,and seeks the general rules of rainstorm and flood formation in the watershed.Statistical investigation results show that the correlation between summer flood and rainstorm is obvious in a reservoir basin,but not significant in autumn.At the same time,the flood at the reservoir dam site is analyzed and calculated by hydrological analogy method,calculation chart of rainstorm runoff in XX Province and new isoline search algorithm in XX Province,and the data of flood is calculated,which provides reliable reference data for flood design of reservoir dam site.
