摘　　要：以阳光大道东向延伸二期工程为背景,针对该工程水中高架桥紧邻瓯北大桥主航道且顺水流方向布置的特点,介绍了目前国内外常用的船撞力计算方法。通过有限元瞬态动力分析方法计算分析,得到了较准确实际的船舶撞击力值。有关经验可供相关专业人员参考。Taking Yangguang Avenue East Extension Phase II Project as the background,aiming at the characteristics of the underwater viaduct adjacent to the main channel of Oubei Bridge and arranged in the direction of downstream flow in this project,the calculation methods of ship collision force commonly used at home and abroad now are introduced.Through the calculation and analysis of the finite element transient dynamic analysis method,the accurate and actual value of ship collision force is obtained.The relative experience can be referred for the relative professionals.

关 键 词：顺水流方向布置 船桥碰撞 船舶速度 有限元瞬态动力分析
