一些桥梁的养护维修任务越来越繁重,结构构件的腐蚀老化、周围环境的影响、人为的破坏、车道通行压力逐渐增大以及屡禁不止的超载问题均造成许多桥梁的结构构件出现部分损坏甚至已经无法满足正常行车安全的要求。碳纤维板的质量轻、抗拉强度高,延展性好,可以对各种结构进行修补,同时不影响桥梁结构的外形和美观。本文根据笔者工作实践,对预应力碳纤维板在桥梁加固工程中的应用进行了分析。
Some bridge maintenance and repair tasks more and more heavy, corrosion and aging of structural components, the impact of the surrounding environment, man-made damage, traffic pressure gradually increases and the repeated overload problems have caused some bridges structural components have been damaged or even no longer Meet the requirements of normal driving safety. Carbon fiber board light weight, high tensile strength, ductility, can repair a variety of structures, without affecting the appearance and appearance of the bridge structure. According to the author’s work practice, this paper analyzes the application of prestressed carbon fiber reinforced plastic in the bridge reinforcement project.
