船舶撞击下重力墩式码头的振动分析方法

针对深海开敞式重力墩式码头，建立船舶—防冲设备—重力式墩的振动系统模型，提出该振动系统位移、转动、船舶撞击力，以及重力墩滑移力和倾覆力矩的振动计算方法，讨论有关参数对动力响应特性的影响，并对某重力墩式码头进行振动分析。

A vibration model of ship-fender-gravity pier system is set up for open sea gravity pier wharf. The methods for calculation the system translations, rotation,ship striking force, sliding force and overturn moment are developed.The effects of the relevant parameters on the dynamic response behavoirs are also discussed and the vibration of a certain gravity pier wharf is analyzed.
