摘　　要：介绍天兴洲大桥的工程特点和设置防撞装置的必要性,提出适合该桥梁防撞要求的等截面桥墩防撞设施,并采用有限元方法对船与该防撞装置的碰撞过程进行了模拟,得出了桥梁设计所关心的技术指标,满足了设计要求。This paper describes the project characteristics of Wuhan Tianxingzhou Changjiang River Road-cum-Rail Bridge, the necessity to provide ship collision protection devices for the Bridge piers and puts forward the constant-section pier protection devices that can accommodate the requirements for ship collision protection of the Bridge, and moreover, the paper also carries out simulation of the process of ships colliding against the protection devices with finite element method and obtains technical indexes that the designers are interested in and that prove to satisfy the design requirements.
