混凝土结构桥梁外观智能检测方法研究

Research on Intelligent Inspection Method for the Appearance of Concrete Structure Bridges

我国大量在役混凝土桥梁在投入使用后不久便出现裂缝等病害,影响桥梁的运营状态与服役寿命,为及时发现桥梁损伤进行加固来确保桥梁健康安全,有必要在桥梁运营阶段开展桥梁外观的定期检测。在桥梁智能化时代,为深化对混凝土桥梁外观检查的认识,综述行业内混凝土结构桥梁外观智能检测方法及研究现状。研究发现远距离非接触式的智能裂缝检测技术是混凝土结构桥梁外观检测的前沿技术,自主图像识别技术是其核心技术,未来智能裂缝检测技术发展的方向将是如何改进裂缝识别算法进一步提高自主图像识别精度。

A large number of concrete Bridges in service appear cracks and other diseases soon after being put into use,which affects the operation status and service life of the Bridges.In order to find out the bridge damage in time to ensure the health and safety of Bridges,in the stage of bridge operation,the use of regular inspection of the appearance of Bridges.In the era of intelligent bridge,in order to deepen the understanding of the appearance inspection of concrete Bridges,this paper summarizes the intelligent inspection methods and research status of concrete structure Bridges in the industry.It is found that the remote non-contact intelligent crack detection technology is the frontier technology of concrete structure bridge appearance detection,and the autonomous image recognition technology is its core technology.In the future,the development direction of intelligent crack detection technology will be how to improve the crack recognition algorithm to further improve the autonomous image recognition accuracy.
