摘要
水文分析中资料特大值的处理,长期以来一直是一个疑难的问题,它直接影响到设计成果的可靠程度。依据数理统计学理论,对暴雨特大值提出重新考证确定重现期的处理方法。并以上海某水利片面雨量为例,对其中一次特大暴雨资料,采用了不同方法进行计算,再按皮尔逊Ⅲ型曲线进行配线,得到计算频率下的设计值,并对此方法进行探讨。
Extraordinary values in the process of hydrology analyzing has been a difficult problem for a long time, which has directly affected the reliability of the design results. Based on the theory of mathematical statistics, in the paper a amethod of determining recurrence interval of heavy rain value its line using P-III type curve distribution was approached. At last, the design value was got under the calculated frequency, and discussed the efficiency of this method.
