【摘要】 基于概率设计原理，对三种由短期冰厚观测资料推求极值分布的方法进行了探讨，分析了这三种方法的适用范围。根据ＪＺ２０－２ＭＵＱ平台上测得的１９９７－１９９９年度日冰厚资料，采用上述三种方法推求年极值冰厚的概率分布，并推算了不同重现期的极值冰厚，可为渤海海上结构物设计提供参考。更多还原

【Abstract】 Based on the probability design theory,the article analyzes three short - term ice - thickness observation data to induce extremal distribution.The author also analyzes the practical range .Accord - ing to the day ice - thickness in the JZ20 - 2MUQ platform from 1997 -1999, using the above 3 meth - ods to induce the year maximum ice - thickness statistical distrbution, the author makes a prediction for the maximum ice - thickness in retum period.This research gives refernce for the marine struc- ture design in the Bohai Sea.更多还原
