| 摘 要： | 阐述以实测或拟合海浪谱为靶谱，用等能量分割法作波面数值模拟，从而利用模拟波面统计分析波高（Ｈ）－周期（Ｔ）联合分布。对波候的Ｈ－Ｔ联合分布、长时段海浪连续记录的Ｈ－Ｔ联合分布以及风浪、涌浪和混合浪的Ｈ－Ｔ联合分布进行了讨论。结果表明，只要已知特征波高和周期，就可反演出模拟波面，进而估测Ｈ－Ｔ联合分布情况，这对了解与各种特征波高对应的周期问题及在海洋工程应用上有一定的参考意义。

| Abstract: | This paper describes that a method of equal energy separation is used in the numerical simulation of wave surface using measured or fitted wave spectra as the trarget spectra. Then,based on the simulated wave surface,a statistical analysis of the joint distribution of wave height and period are made. Some joint distributions are discussed, such as the H-T joint distribution of wave clime, the H-T joint distribution of longer time continuous wave records, the H-T joint distribution of wind-wave, swells and mixed waves.The results indicate that under the condition of known characteristic wave heights and periods, the wave surface may be recovered and used to estimate H-T joint distribution which has reference value to understand the problems of various characteristic wave heights that correspond to periods as well as marine engineering applications. |
