预应力碳纤维布加固桥梁应用技术研究

Research on Application Technology of Prestressed Carbon Fiber Sheet in Bridge Reinforcement

近年来,随着我国国民经济的迅速增长,公路桥梁事业迈入了一个全新的发展阶段,各种在建和已建桥梁的规模不断刷新着世界记录,取得了令人瞩目的成绩。当前我国很多早期修建的桥梁工程已步入大修加固阶段,预应力碳纤维布的应用,可以达到良好的应用效果。基于此,本文依托某桥梁工程,确定了加固方案,并对加固施工工艺和荷载试验评估情况进行了分析与探讨,以期进一步推动预应力碳纤维布在桥梁加固中的应用。

In recent years,with the rapid growth of my country's national economy,the highway and bridge industry has entered a new stage of development.The scale of various bridges under construction and already built has continuously set world records and achieved remarkable results.At present,many early-built bridge projects in my country have entered the stage of major repair and reinforcement.The application of prestressed carbon fiber cloth can achieve good application effects.Based on this,this article relies on a certain bridge project to determine the reinforcement plan,and analyzes and discusses the reinforcement construction technology and load test evaluation,in order to further promote the application of prestressed carbon fiber cloth in bridge reinforcement.
