In recent years, ship-bridge collision accidents occur frequently .The increasing number of ship col-lision accidents has put forward a new urgent requirement to the study of anti-ship collision .The current situation of ship-bridge collision research was introduced , using LS-DYNA software , established a ship impacting bridge pier computational model , and conducted the numerical simulation of bridge pier with and without anti-collision device respectively , compared the results of the evolution of the impact force , displacement deformation and energy ab-sorption , and carried out the detailed analysis of the result , obtained the corresponding conclusions about the effect of anti-collision.The research results have certain reference significance to the design of anti-collision device of bridge structure in the future .%近年来船舶撞击桥墩的事故频繁发生，日益增多的船撞桥事故对桥梁防船撞研究提出了新的迫切要求。介绍了船桥碰撞研究现状，运用LS-DYNA软件建立了船舶撞击桥墩的计算模型。分别对无防护装置和有防护装置进行了数值模拟，对比其碰撞力演变、桥墩位移变形和能量吸收等结果；并对其进行了详细分析，得到了关于防撞效果的相应结论。研究结果对今后桥梁结构的防撞装置设计有一定的参考意义。
