由于桩基平台具有抵御波浪、地震的能力,特别适于海洋石油的开采,它几乎分布于世界各个海域,迄今已有40余年的历史。 桩基平台受到波浪、地震巨大载荷的作用,工程设计时必须进行动力响应分析,但是在平台动力分析时,水动力阻尼的确定是个困难问题。 国内外学者对海洋平台水动力阻尼的研究现状可简要归纳为:(1)平台处于海水环境中,分析平台动力响应时不能忽视水动力阻尼的影响;(2)水动力阻尼仍可按莫里森
Because the pile foundation platform has the capability of resisting waves and earthquakes and is particularly suitable for the exploitation of offshore oil, it has been distributed in almost all areas of the world for nearly 40 years. The pile platform is subject to the huge load of waves and earthquakes. The dynamic response analysis must be carried out in engineering design. However, the determination of hydrodynamic damping is a difficult problem in the platform dynamic analysis. Domestic and foreign scholars on the hydrodynamic damping of the offshore platform status can be summarized as follows: (1) the platform in the seawater environment, the dynamic response of the platform can not ignore the impact of hydrodynamic damping; (2) hydrodynamic damping can still be Morley Sen
