概述了东海近海风与浪的基本情况。重点对国家海洋与东海沿岸具有30a测波记录的5个站实测资料进行了年极值统计分析,选用三参数的P-Ⅲ型分布与四参数的指数Γ分布,通过最小二乘法与优选参数法相结合的寻优适线法进行分布参数估计,最后得出东海五站不同重现期的设计波要素,并对超过破波极限值进行订正。 The basic situation of coastal wind and waves in the East China Sea is summarized. Emphasis on the national ocean and the East China Sea coast with 30a records of the measured data of 5 stations for the annual extreme statistical analysis, the choice of three parameters of the P-Ⅲ type distribution and the four parameters of the index Γ distribution by least squares method with the preferred parameters Method to find the distribution parameters of the optimal fitting method. Finally, the design wave elements of five stations in the East China Sea at different recurrence periods are obtained and the surpassing of the breaking wave limit value is revised.
