摘    要:将大型浮码头简化为梁模型,考虑规则波和非规则波,研究了其动力响应及可靠性指标计算方法。计算了长700m浮码头的动力响应及可靠性指标,得到了浮码头长度方向规则波作用下弯曲应力的幅值分布,以及非规则波作用下浮码头底板的可靠性指标。计算表明,本方法可用于大型浮码头动力响应预报及极限强度分析。

关 键 词:浮码头  底部板架  极值波浪荷载  动力响应  可靠性分析  振动  极限强度

Abstract:Simplifying a very large pontoon(VLP)to a beam model and considering the action of regular and irregular waves,we studied the calculation methods of dynamical response and reliability index of VLP.After studying the dynamical response and reliability index of a 700 m long pontoon,we obtained the contribution of the amplitude of the bending stress in the longitudinal direction of the pontoon under the action of the regular waves and the reliability index of the bottom panel of the pontoon under the action of the irregular waves.It is shown that the method can be employed in the prediction of dynamics response and analysis of extreme strength of VLP.
Keywords:pontoon  stiffened panel on the bottom  extreme wave loads  dynamic response  analysis of reliability
