摘要
近年来,桥梁上部结构遭受超高船舶撞击的事故时有发生,事故往往带来严重的经济损失甚至人员伤亡,其后果的严重性不容忽视。因此,研究超高船舶与桥梁上部结构的碰撞问题具有现实意义。然而,目前研究重点多是围绕船舶撞击桥梁墩柱、承台等下部结构开展,针对船舶与桥梁上部结构碰撞问题的研究工作相对较少。本文介绍了近年来对于超高船舶撞击桥梁上部结构问题的相关研究成果,主要包括不同类型桥梁上部结构碰撞灾害的典型事例,碰撞过程中桥梁主梁的破坏模式,船撞力计算公式与影响因素的研究,多种桥梁上部结构防船撞设施的介绍和比较等,能够为今后对于超高船舶撞击桥梁上部结构问题的相关研究提供参考。
In recent years,accidents of bridge superstructure impacted by super-high ships occur frequently,and the economic losses and casualties caused by the accidents cannot be ignored.Therefore,it is of practical significance to study the collision between super-high ships and bridge superstructure.However,the current research focuses on the impact of ships on bridge piers,caps and other substructures,and there is less research on the collision between ships and bridge superstructures.The research results in the field of super-high ships impacting bridge superstructures in recent years were introduced,mainly including typical accidents of different types of bridge superstructure collision disasters,the failure mode of bridge girder when superstructure collided.The calculation formula and influencing factors of ship collision force were researched,as well as the introduction and comparison of various bridge superstructure anti-collision facilities,which would provide reference for the related research on the impact of super-high ships on bridge superstructure in the future.
