纤维增强聚合物公路桥梁的维护和无损检测方法

Summary of Maintenance and Inspection Methods for Fiber Reinforced Polymer(FRP)Highway Bridges

基于纤维增强聚合物(FRP)建造的桥梁具有轻质高强、耐腐蚀以及环保等特点,已被广泛应用于高速公路、铁路和街道的立交桥上,但由于长期的静态和动态载荷,FRP公路桥梁的损伤是不可避免的。基于此,综述了FRP公路桥梁的结构维护方法和无损检测方法,并系统性地分析了这些方法的优缺点和成本,从而为FRP公路桥梁结构的有效维护和检测提供参考。

Bridges built on fiber reinforced polymer(FRP)have the characteristics of light weight,high strength,corrosion resistance and environmental protection,and have been widely used in overpasses of highways,railways and streets.However,due to long-term static and dynamic loads,the damage of FRP highway bridges is unavoidable.Based on this,this paper summarizes the structural maintenance methods and detection methods of FRP highway bridges,and systematically analyzes the advantages,disadvantages and costs of these methods,so as to provide a reference for the Effective maintenance and detection of FRP highway bridge structures.
