Characteristics and Applications of Non-destructive Testing Technology in Bridge Engineering

Abstract

The construction of bridge projects can promote economic exchanges between different regions and provide convenient transportation for people. The application of non-destructive testing technology has effectively improved the overall quality of bridge inspection work, providing a reliable guarantee for the development of the transportation industry. This paper elaborates on the specific principles, characteristics, and research status of ultrasonic testing technology, three-dimensional laser scanning technology, and radiographic testing technology in practical operations, and comprehensively compares the advantages and disadvantages of the three non-destructive testing technologies in bridge engineering. Ultrasonic testing technology has simple operation and low cost, but the detection results are not intuitive enough; three-dimensional laser scanning technology has high accuracy and good digital compatibility, but its cost is relatively high; Radiographic testing technology has a wide range of applications, and the detection results are relatively intuitive, but the detection efficiency is low. Finally, it is discussed that the current difficulties in using non-destructive testing technology in bridge engineering lie in high costs and inadequate integration. It is proposed to incorporate non-destructive testing technology into bridge design planning to form a more complete system.
