【摘要】 对作为海洋工程研究难点的海洋平台的动力响应分析问题的研究现状进行了较全面的综述。首先对平台结构的模型化、桩-土相互作用的模型化两个海洋平台动力响应分析中最重要的建模问题进行了讨论,然后介绍了动力方程中波浪荷载的计算及动水阻尼线性化的方法,并给出了地震、波浪联合作用下海洋平台动力响应分析的动力方程,最后对该研究领域中有待深入研究的问题提出了作者的观点。更多还原

【Abstract】 This paper presents a research advance of dynamic analysis of offshore structure,which is a complicated research focus of ocean engineering.A review of modeling of platform and modeling of pile-soil dynamic interaction are summarized in this paper.Calculation of wave load and linearization of hydrodynamic damp for dynamic analysis of offshore structure are also discussed.The motion equation of offshore structure under simultaneous loading by wave load and earthquake motion is introduced,and the future development trend of this issue is discussed.更多还原
