纤维增强塑料(FRP)在桥梁建设中的应用现状

FRP applications in bridge construction

近年来,FRP由于其优良的材料性能,在桥梁结构中得到了广泛应用,相关研究亦取得了丰硕成果.文中对FRP构件、FRP加筋混凝土、FRP维修和加固以及FRP在新建桥梁结构中的应用这四个方面进行了分类比较与总结.最后回顾了目前FRP应用规范和规程,指出了有待进一步解决的问题.

Due to the advantageous properties of FRP materials, FRPs have found increased applications in bridge construction in recent years, and have obtained plenty study result. The paper compares and concludes the research and application results of FRP materials in bridge construction on the base of FRP components, FRP-reinforced concrete, FRP retrofit, and FRP new structures. Finally, FRP codes and guidelines are reviewed, and some proposals are put forward.
