| 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 thatneither damage the pie... |
