摘　　要：利用青岛海洋大学海洋实验室现代化的大型水槽，设计进行了多种海浪强度下，由深水传入近岸不同坡度水底上的变浅随机海浪的模型实验。依据实验资料统计分析结果表明：对近岸变浅随机海浪而言，其波高分布不再符合Ｒａｙｌｅｉｇｈ分布，与Глуховский的经验分布也有差异，它不仅与参量Ｈ＊＝Ｈ／ｄ有关，且与表征深水海浪的波形特征量Ｈ０／Ｔ２０有关，并获得其经验关系，为实验应用变浅随机海浪的波高统计分布提供了可能。The experiments of random shoaling sea waves, which propagate from deep water on different beach slopes, were designed and undertaken under several wave strengths using the modern large wave flume of the physical oceanography laboratory of Qingdao Ocean University. On the basis of laboratory data and analytical results, it is shown that for nearshore random shoaling sea waves the distribution of wave heights is not in agreement with Rayleigh distribution and differs from empirical distribution. This distribution of wave heights not only relates to the parameter H =H/ d ,but also to the characteristic parameter H 0T 2 0 which represents the form of deep water waves. The empirical relationship thus obtained, therefore. Provides the possibility of practical application of the statistical distribution of heights of random shoaling sea waves.
