摘要： A method and an apparatus (21) are provided for automatically measuring the interior dimensions of tunnels (20). The apparatus is mounted on an inspection vehicle and comprises a plurality of ultrasonic transducers (12, 13, 14, 15) which are arranged to form an imaginary template a predetermined distance from the tunnel wall (20). The transducers (12, 13, 14, 15) are periodically operated by a computer (C) to derive measurement information as the inspection vehicle moves through the tunnel. The results of each measurement are stored by the computer (C) for subsequent analysis.
