摘　　要：阐述了船舶撞击桥墩的危害性及桥墩防护的必要性,并对桥墩的防撞装置进行了系统的分类和评述,总结目前国内外桥墩防撞装置的优缺点,并给出了关于防撞装置的设计思路,研究了国内外船桥碰撞和桥墩防撞装置的情况,以及防撞墩非线性有限元分析方法。The paper expounds the damage of the ship-bridge collision and the necessity of protected piers, classifies and comments all kinds of protection devices of bridge piers, then summarizes the merits and shortcomings of the current protection devices. The paper gives design ways on the protection device, studies the nonlinear FEM computation technique and process of the nonlinear stability problem, and the fundamental theory for mechanism of collision and calculate of collision power is studied.
