Application of Nondestructive Testing Technology in Quality Evaluation of Plain Concrete and RC Structures in Bridge Engineering: A Review

The development and application of nondestructive testing technology for prestressed reinforced concrete structures in the field infrastructure construction were summarized this study via analysis relevant literature worldwide. detection methods, principles, instruments quality evaluation analyzed compared, based on which, acoustic emission technology, impact echo ultrasonic infrared thermography ground-penetrating radar piezoelectric transducer X-ray summarized. Additionally, advantages, disadvantages, scope each method focused upon comparatively. It is indicated that further improvement visualization, accuracy, efficiency most technologies available by optimizing algorithm combining artificial intelligence with neural network deep learning, precise positioning, imaging defects structures. results can provide technical reference research inspection
