摘要: 介绍了一种具有自定位功能的弱接触连接构造和具有高消能效果的新型FRP桥墩防撞浮箱结构,它可适用 于桥区水位变幅较大和墩的抗力远低于其设防船撞力的桥墩防撞保护工程,可获得“既不伤墩、又少伤船、还少结 构自伤”的最佳防护效果,是实现桥墩“和谐防撞”与“长效防撞”的技术创新尝试。

Abstract: A late-model FRP floating pontoon protection structure with self-location function,weaker contact joint formation and higher energy dissipating effect for bridge piers in the ship collision is presented in this paper.The structure applies to the pier protection engineering where the water level around the bridge fluctuates largely or the actual resisting capability of the pier is insufficient for its designing ship collision force.With the structure, the optimized protection effect that “neither damage the pier nor harm its self structure and ship structure too much”can be achieved.It can be regarded as a trial of technical innovation to realize the“harmonious protection”and“long-term protection”for the pier in the ship collision.

Key words: bridge pier, protection floating pontoon in ship collision, FRP, periphery box structure, cylindrical thin-shell lining component
