我国运营铁路隧道总体规模巨大，传统隧道检测方式难以满足大规模运营隧道检测及时、高效的需求，融合隧道检测新技术、优化运营铁路隧道既有检测方式是运营铁路隧道检测降本增效的关键。基于以上问题，对中国、日本及韩国隧道检测技术进行调研，从图像类、探测类以及集成综合类3个方面梳理中日韩隧道检测技术发展现状。提出运营铁路隧道检测技术以快速综合检测、数据智能化判释、隧道状态协同评估为主的发展趋势，分析适用于我国运营铁路隧道实际情况的隧道检测模式，提出应重视铺轨前的隧道检测，确保隧道初始状态信息的全面和真实性，加快建设隧道状态信息库，基于快速、综合、智能化的隧道检测技术体系，实现运营期铁路隧道的动态周期检测，以实现运营隧道降本增效。
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.
