纤维复合材料在桥梁工程中的应用研究

Application of Fiber Composites in Bridge Engineering

桥梁工程往往处于恶劣的环境中,且制约因素多、受力条件复杂,传统的钢筋与混凝土等建桥材料逐渐显现出不足,如跨度难以实现突破、桥梁使用耐久性较差、维修养护成本高等。作为一种新型复合材料,纤维复合材料(FRP)具有优异的综合性能,能很好地满足桥梁建设的多数需求。基于此,该文在介绍FRP材料基本特性的基础上,总结了其在桥梁工程中的应用优势,着重阐述了FRP材料在桥梁工程中的具体应用方式。最后,对FRP复合材料的未来发展趋势提出了几点展望。

Bridge engineering is often in a bad environment,with many restrictive factors and complex stress conditions.The traditional bridge building materials such as reinforcement and concrete gradually show deficiencies,such as difficult to achieve a breakthrough in span,poor durability of bridge use and high maintenance cost.As a new composite material,fiber reinforced polymer(FRP)has excellent comprehensive properties and can well meet most needs of bridge construction.Based on this,on the basis of introducing the basic characteristics of FRP,this paper summarizes its application advantages in bridge engineering,and focuses on the specific application mode of FRP in bridge engineering.Finally,some prospects for the future development trend of FRP composites are put forward.
