随着波谱理论研究的发展,各种海工结构及船舶的荷载及其内力分析也日趋应用不规则波的计算方法。目前对于外海码头在波浪作用下的船舶撞击荷载还应用规则波的研究方法,对其应用不规则波分析方法的途径以及在考虑波谱作用后会有怎样的结果等问题目前还较少研究。本文试图对此问题进行初步的分析。 With the development of spectroscopic theory research, the calculation methods of irregular wave are increasingly applied to the analysis of loads and internal forces of various offshore structures and ships. At present, there are still few studies on the application of regular wave to the impact load on ships under the action of waves at the Outer Harbor, the ways of applying the irregular wave analysis method and the result after considering the spectral action. This article attempts to conduct a preliminary analysis of this issue.
