预应力碳纤维板加固技术在旧桥加固中的应用

Application of Prestressed CFRP Plate in Old Bridge Reinforcement

结合某连续梁桥的工程概况,对该桥进行了外观及荷载试验检测,提出了采用预应力碳纤维板加固方案。利用有限元模拟,对比分析了加固前后的桥梁荷载,结果表明,该桥加固后承载力显著提高,该加固技术的有效性得到验证。

Combining with the engineering general situation of a continuous beam bridge,this paper made appearance and load test detection to this bridge,and put forward the prestressed CFRP reinforcement method.By the finite element software,compared and analyzed the bridge load before and after the reinforcement,pointed out that the bearing capacity of bridge after reinforcement increased significantly,verified the effectiveness of the reinforcement technology.
