Laser imaging method has been applied to draw up the crack development instead of man-made tunnel inspection. However, with the existing state, laser imaging method is applied only for the observation of tunnel lining surface, or applied limitedly for above the level of the spring line. We have pay attention to the full-rotating laser scanning method which has an ability to measure the state such as cracks, temperature distributions, of the whole tunnel lining surface included floors and tunnel cross sections, and studied an application for the road tunnel.
The effectiveness of this method to the tunnel inspection and management, has been confirmed through the above mentioned results. Furthermore, this method is able to apply water tunnel and shed.
