【摘要】：基于實測極值流量系列進行水文頻率分析時,為了提高系列的代表性及洪水估計的可靠性,常將歷史洪水信息融合到實測系列構(gòu)成不連續(xù)樣本。考慮到目前給出的不連續(xù)樣本經(jīng)驗頻率計算方法多數(shù)是針對單個調(diào)查期,本文提出了適用于多個調(diào)查期不連續(xù)樣本的經(jīng)驗頻率計算方法,同時推導了均值(EX)和變差系數(shù)(Cv)的矩法計算公式,并將該方法應用于某水文站年洪峰系列的頻率分析中。
[Abstract]:In order to improve the representativeness of the series and the reliability of flood estimation, historical flood information is often fused to the measured series to form discontinuous samples when the hydrological frequency analysis is based on the series of measured extreme discharge. Considering that most of the methods for calculating the empirical frequency of discontinuous samples are for a single investigation period, an empirical frequency calculation method suitable for discontinuous samples in multiple investigation periods is proposed in this paper. At the same time, the formula of moment method for calculating the mean value and variation coefficient is derived, and the method is applied to the frequency analysis of the annual Hong Feng series of a hydrologic station.
