摘　　要：桥船防撞结构是保护桥梁和船舶免受碰撞事故影响的重要装置。本文采用有限元方法,对为满足航道通航升级而设计的楔形桥梁防撞结构进行了船舶撞击仿真模拟,分析了不同撞击位置、不同撞击角度下防撞墩的应力分布情况。Bridge-ship anti-collision structures is an important device to protect bridges and vessels from collision accidents.With the increasing growth of water transportation and the continual expansion of shipping activities,it has become particularly important to design reliable bridge-ship collision prevention structures.In this article,a finite element software is used to analyze a separated wedge bridge anti-collision structure designed for upgrading the navigational capacity of a certain bridge.The stress distribution of the collision prevention piles when the vessel collides under different conditions was calculated.
