Research and Application of Ballastless Track Ultrasonic Imaging Technology
The service performance and duration of the track structure will be affected by the diseases such as the loss of blocks between the layers of the ballastless track plate and the local cavitation.Phased array ultrasound technology,synthetic aperture ultrasound imaging technology,full focus ultrasound imaging technology based on full matrix and half matrix data acquisition methods are introduced,and their principles and applications in the detection of concrete structures and ballastless tracks are briefly described.After analysis,the joint detection and mutual verification of ultrasonic detection technology and the latest ultrasonic imaging technology to enhance the accuracy of the detection structure has become a new direction.
