海浪周期在海洋工程设计中有着重要作用,而不同的海洋工程设施在设计时所选用的周期参数也不同,因此不同周期间的换算关系也就显得尤为重要。本文利用南海北部油气田区1 a的实测海浪周期数据,研究了其谱峰周期、有效周期、跨零周期和最大波高周期等的相互关系,并与相关规范和文献研究结果进行对比,给出了南海海浪周期间的关系式,从而为海洋工程设计提供了支持,也为南海海浪周期关系研究提供了参考。
The wave periods play an important role in marine engineering design, especially for the relationships of ocean wave periods. In this study, one year measured wave period data had been applied to investigate the relationships of different wave periods, such as the spectral peak period, significant wave period, the zero-crossing period, the maximum wave period, and so on. The results of this study were compared with those from some literatures and some correlative standards. The corresponding formulae of different wave periods were put forward. Consequently, our results provide support for the marine engineering design and the study of the relationship between wave periods in the South China Sea.
