摘要
采用P-III型分布及极值I型分布,研究了沿海地区设计潮位计算方法。阐述了资料的一致性检验的方法。结合坎门站潮位资料,对比了两种方法的计算效果。结果表明,两种方法对不同重现期设计值的估计结果相当,但P-III型分布计算时参数的选取与习惯用法不符,因此,建议采用极值I型分布进行设计潮位计算。
Procedure applying Pearson Type Three distribution (P-III) and Extreme value type I distribution (EV-I) to designed tide level calculation is studied in this paper to describe the testing methods of data coherence. Combining the tide data of Kanmen station, the two methods of P-III distribution and EV-I distribution are compared. Results indicate that P-III distribution is compatible to EV-I distribution in estimating designed values. But, the adopted parameters of P-III distribution does not accord with tradition, so, the EV-I distribution was recommended for designed tide level calculation.
