目前,各种海洋工程规范采用的有效波高H_(1/3)与最大波高H_(max)的关系各不相同,它们采用窄谱条件下的理论关系或经验关系。本文针对北部湾海区的实际波浪状况,利用测波资料计算了谱宽参数的分布规律,然后在宽谱的条件下分析并确定了最大波高H_(max)与有效波高H_(1/3)的关系随谱宽度参量ε与波个数N的变化规律,最后结合北部湾有效波高的长期分布计算出不同重现期约设计波高。
At present, the relationship between the effective wave height H_ (1/3) and the maximum wave height H_max adopted by various ocean engineering norms is different, and they adopt the theoretical relationship or empirical relationship under narrow spectrum conditions. In this paper, according to the actual wave condition in Beibu Gulf, the distribution law of spectral width parameters is calculated by using the wave data. Then the maximum wave height H_ (max) and the effective wave height H_ (1/3) Relationship between spectral width parameter ε and the number of waveforms N, and finally calculated the long-term distribution of effective wave height of the Beibu Bay.
