新型FRP桥墩防撞浮箱有限元仿真分析

Finite element analysis of late—model frp floating pontoon for bridge piers in ship collision

随着航道通航量增加,对桥墩的防护不断有新方法引入,基于在桥墩防撞结构中首次引入FRP新型材料的防撞浮箱有限元仿真分析,探索这种新型结构在桥墩防撞方面的优势,应用FRP防撞浮箱能达到"既不伤墩、又少伤船、还少结构自伤"的设计目的,实现长效防撞。

With the rising volume of navigation channels, new methods for the protection of bridge piers were introduced. This paper, based on the firstly introduced finite element analysis of FPR floating pontoonfor pro- tection of bridge piers in the ship collision, explores the advantages of this new structure in collision avoidance of bridge piers. With the usage of FPR floating pontoon, the design goal of ＂no harm to piers, no harm to ships, decreased self-hurt of the structure＂ can be obtained so as to achieve long-term protection.
