Abstract: 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.
