| 摘 要： | 基于实测极值流量系列进行水文频率分析时,为了提高系列的代表性及洪水估计的可靠性,常将历史洪水信息融合到实测系列构成不连续样本。考虑到目前给出的不连续样本经验频率计算方法多数是针对单个调查期,本文提出了适用于多个调查期不连续样本的经验频率计算方法,同时推导了均值(EX)和变差系数(Cv)的矩法计算公式,并将该方法应用于某水文站年洪峰系列的频率分析中。

| Abstract: | Adding historical floods into sequential series is a common method to improve representativity and reliability of flood se - ries in hydrologic frequency analysis. However, the methods of empirical frequency calculation are mainly used for sequential series and discrete series with single investigation period at present. In this paper, the method of empirical frequency calculation and formula for estimating mean value based on moment method for discrete series with multi-investigation periods were presented, which have been applied in frequency analysis of the flood peak series at a station. |
