Ir.; Wang, Yudi	Comparison Study of Ultrasonic and Surface Wave Methods for Crack Depth Detection in Concrete Panels	2023	5	.pdf	application/pdf	2244	96	52	A total of 114 cracks were detected using both ultrasonic and surface wave methods, and the results show that the detection values of ultrasonic method are smaller than those of surface wave method. In addition, the data of 9 cracks that penetrated the concrete panel were compared and analyzed, and the results show that the detection error of ultrasonic method is between -22% and 41%, while that of surface wave method is between -7% and 27%.	cache/ajst-7802.pdf	txt/ajst-7802.txt
