The detection equipment for the state of railway tunnel lining is a vehicle-mounted complex equipment which is supported by the special purpose vehicle of railway and integrates with various sophisticated detection device including laser clearance measurements, ground penetrating radar (GPR), laser imaging device of the lining surface, video monitoring system, therefore it can be efficient, accurate and comprehensive completion of detection of operating tunnel lining. In this paper according to relevant norms, standards for assessing the state of operating railway tunnel and current detection technologies of tunnel lining, the functions and components of detection equipment are determined and the main performance parameters of device and the key technologies are deeply analyzed and studied, to speed the development of equipment and provide the necessary technical support.
