采用纤维布或纤维薄板 (FRP)对混凝土结构进行加固和修补是一种先进的补强方法。课题组在前期的理论和室内实验研究的基础上 ,采用自行编制的碳纤维、芳纶纤维和高强玻璃纤维薄板 ,对 32 1国道广东境内某一破损比较严重的混凝土刚架拱桥进行加固。介绍该桥加固工程的设计与施工方法。加固后的动静载试验结果及通行情况表明 ,采用该文所示方法加固旧危桥是有效的 ,且具有优越的性能价格比 Reinforcement and repair of concrete structures with fiber cloth or fiber sheet (FRP) is an advanced method of reinforcement. On the basis of the previous theoretical and laboratory experiments, the research team used a self-made carbon fiber, aramid fiber and high-strength glass fiber sheet to reinforce a damaged concrete rigid frame arch bridge in the territory of Guangdong Province. Describe the design and construction of the bridge reinforcement project. After the static and dynamic load test results and the passage of the situation shows that the method used in this article to strengthen the old dangerous bridge is effective and has excellent cost performance
