T hrough analysis comparison of detection technology and equipments for tunnel lining and bottom at home and abroad. By combing with the need of railway tunnel lining state detection in China,the main technical indexes and key technology problems of geological radar system on the vehicle were discussed,technical solution of fast inspection car for tunnel state w as presented,and inspection car for the railw ay tunnel lining state w as developed, which could detect 5 lines of tunnel lining and 3 lines of tunnel bottom at the same time and achieve the nondestructive testing of whole tunnel. T he inspection car can reach a maximum detection speed of 10 km/h and has been used in some new and existing railways successfully,which could greatly improve the speed and efficiency of railway tunnel nondestructive detection and reduce the labor intensity.
