Abstract: A new dynamical analysis is given in this paper,which deals with floating pier with stay-bar system that is impacted by a berthing barge.First,suppose that a barge,floating pier and stay piers are combined into a compound system,a stiffness matrix of the system is inferred and the damping is counted.Then,according to the imitial velocity of the system impacted by barge,the impact force,the stress of stay-bars and the motive dip of pontoon are calculated by means of vibration analysis of the system.This supplies engineering analysis with a reasonable calculation method.

摘要： 本文首次提出撑杆系统的浮码头在船舶靠岸撞击问题的动力分析方法,假定船舶-浮码头-撑墩组成复合体系,导出系统的刚度矩阵,计入阻尼影响,由系统在船舶给予初速度的振动,来确定撞击力、撑杆内力以及趸船的动倾角,为工程提供较合理的计算方法。
