海浪的波谱特征分析对认识海浪有重要的意义,因为海浪谱反映了海浪的结构成分。这对海工建筑、海洋运输、船舶制造、海浪预报和海浪模拟等均有重要的实用意义。 波群是伴随海浪经常出现的一种自然现象,且经常伴随大浪的出现而出现。实践证明,波群具有极大的破坏力,其破坏性远比单个波大得多,它是海浪破坏海工建筑物的重要因子,许多防波堤的破坏并非是由单个波的作用,而是由相继出现的几个大波(波群)作用的结果。早先,人们对波群这种习见的现象研究甚少。自1974年葡萄牙锡尼斯港深水防波堤的破坏之后,对波群的研究才日益受到重视。
The analysis of the spectral characteristics of the waves is of great significance for the understanding of the waves because the wave spectrum reflects the structural components of the waves. This has important practical significance for offshore construction, marine transportation, shipbuilding, ocean wave forecasting and wave simulation. Wave groups are a natural phenomenon often accompanied by waves and often occur with the appearance of waves. Practice has proved that the wave group has great destructive power. Its destructiveness is far greater than that of a single wave. It is an important factor that waves destroy marine structures. Many of the breakwaters are not destroyed by a single wave but by Several major waves have emerged (wave group) the result of. Earlier, there was little research into the phenomenon of wave grouping. Only after the destruction of the deepwater seawall in Port of Ningis in Portugal in 1974 is the study of the wave group increasingly valued.
