Abstract
This article comprehensively analyzes the current research status of non-destructive testing and reinforcement technology for steel structure bridges at home and abroad.It elaborates on non-destructive testing technologies such as ultrasonic testing,radiographic testing,magnetic particle testing,and penetrant testing,as well as the principles and application scenarios of reinforcement technologies such as increased cross-section reinforcement,external prestressing reinforcement,carbon fiber reinforced composite material(CFRP)reinforcement,and steel structure node reinforcement.The benefits of these technologies are analyzed through practical cases.Non destructive testing and reinforcement technology can effectively ensure the safety of steel structure bridges,reduce traffic interruptions,and have significant social,environmental,and economic benefits.However,it still faces challenges such as detection signal interference,material coordination,construction quality control,and durability evaluation.This article provides precise decision-making basis and efficient technical guidance for bridge engineering personnel,clarifying that future technology research and development should focus on the development of new detection sensors and materials,the application of intelligent construction and monitoring technology,and the improvement of the durability evaluation system for reinforced structures,in order to help build a better maintenance technology system for steel structure bridges.关键词
