利用青岛海洋大学物理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实验．依据实验资料分析结果表明，对变浅非正态海浪过程而言，其波面高度分布取Gram－Charlier级数前3项，所得结果与实验分布符合良好．该分布中a、3个参量是测点水深和波浪强度的函数，并获得了与无因次参量Hs／d之间的经验关系，为预测变浅随机海浪的波面高度分布提供了可能．
Using the large modernized large-scale sink at Qingdao Ocean University Physical Ocean Laboratory, a series of experiments were carried out to investigate the effects of various sea-wave intensities on the shallow-water stochastic ocean waves at different slopes of the nearshore. According to the experimental data, the results show that for the shallowing non-normal wave process, the wave height distribution of the first three Gram-Charlier series, the results obtained and the experimental distribution in good agreement. The three parameters α and β of the distribution are a function of water depth and intensity of the measuring point and obtained the empirical relationship with dimensionless parameter Hs / d, which makes it possible to predict the wave height distribution of the shallow ocean.
