Abstract：Extreme wave height is an important environmental condition in offshore and ocean engineer-ing design,and the study of the design values of wave height is of great significance.Based on the tra-ditional compound extreme value distribution,this paper classified the maximum wave height data of the wave disaster process according to their source,and selected the optimal extreme value distribution by fitting various wave height sequences respectively.Finally,the design value of wave height was cal-culated jointly and compared with the design value of Poisson compound extreme value distribution model and annual extreme value model.The results showed that the Pearson type 3 distribution had the best fitting effect on the wave height in the Beihai area.Compared with the traditional model,the de-sign wave height of the multi-source compound extreme distribution model was more conservative.The multi-source compound extreme distribution model proposed in this paper can provide some reference for the design of offshore and ocean engineering.
