【摘要】：对收集到的响水海域实测双峰谱型海浪资料进行谱分析和统计分析,探讨了双峰谱型海浪的波高分布、周期分布以及波高与周期的联合分布,认为用单峰谱型海浪的研究成果来描述双峰谱型海浪已不再适宜,并根据响水海域实测波浪资料,提出了双峰谱型海浪的波高、周期的经验分布式。通过对双峰谱型海浪资料进行谱分析,计算了若干与谱宽有关的波谱参量,并与合田良实的实测结果进行对比。最后还对双峰谱型海浪的谱特征值与跨零特征值进行了比较,认为对于双峰谱型海浪,由谱法计算的有效波高与由跨零法计算的有效波高相差不大;而对于平均周期,谱法要略小于跨零法。
[Abstract]:Spectral analysis and statistical analysis are carried out on the collected wave data collected in the sea area with two peaks, and the distribution of wave height, periodic distribution and the joint distribution of wave height and period are discussed. It is considered that it is no longer suitable to use the research results of single peak spectral wave to describe the double peak wave. According to the measured wave data in the sea area, the empirical distribution of wave height and period of the wave with double peak spectrum is proposed. Based on the spectral analysis of the two-peak wave data, some spectral parameters related to the spectral width are calculated and compared with the measured results of Hidehida. Finally, the spectral eigenvalues of bimodal waves are compared with those of cross-zero waves. It is considered that for bimodal waves, the difference between the effective wave heights calculated by the spectral method and the effective wave heights calculated by the zero-span method is not significant, but for the average period, The spectral method is slightly smaller than the cross-zero method.
