Traditional
tunnel inspection methods struggle to satisfy the demands of largescale
tunnel inspection in a timely and effective manner in China owing the large
number of operational railway tunnels. In this study, a costeffective and efficient railway tunnel inspection is realized by developing
the new tunnel inspection technology and optimizing the existing detection
methods. First, the tunnel inspection technologies used in China, Japan, and
South Korea are investigated, and the stateoftheart of the tunnel inspection technology
development is introduced from the aspects of image inspection technology, nondestructive detection technology, and integrated inspection
technology. Based on the current situation, the development trends in
operational railway tunnel inspection technology, rapid comprehensive
inspection, intelligent data interpretation, and collaborative assessment of
tunnel status are proposed, and the tunnel inspection mode applicable to the
actual situation of operational railway tunnels in China is analyzed. Results show
that tunnel inspection should be focused upon before tracklaying. Comprehensive and real tunnel initial state information
should be ensured, and the construction of tunnel state information database
should be speeded up to realize the dynamic cycle detection of railway tunnels
in the operation period, reduce cost, and increase efficiency based on rapid,
comprehensive, and intelligent tunnel detection technology system.
