碳纤维技术在旧桥加固中的应用研究

Application research of carbon fiber technology on old bridge reinforcement

分析了外贴碳纤维布加固梁的承载能力、破坏形式,结果表明:外贴碳纤维布加固不仅能有效地提高钢筋混凝土梁的承载能力,而且可以大幅度地提高其安全储备,是一种有效的桥梁加固方法。

The author analyzes the loading capacity and destroying way of reinforcing beam based on the externally bonded carbon fiber close, results show that externally bonded carbon fiber close can not only enhance the loading capacity of the high strength reinforcement concrete beam effectively, but also improve its safety margin greatly, and is a kind of effective bridge reinforcement method.
