以近些年我国城市轨道交通隧道病害检测技术为对象，总结目前针对不同隧道病害所采用的常用检测技术以及新型检测技术，其中新型检测技术包括传感器检测技术、数字照相检测技术、激光扫描检测技术以及多功能集成的隧道检测车技术。详细介绍这几种新技术的原理，对比这几种检测技术的适用范围（检测病害类型）以及在环境条件、检测频率、处理速度、费用、人工依赖程度等各个方面的优势与劣势，表明自动化、实时化和集成化将是未来隧道检测技术发展的重要方向，传统人工+设备的检测模式将逐步转化为设备自动检测，技术人员的主观判别将逐渐被自动化检测代替；而集成化的检测设备也必将成为未来隧道检测设备的发展趋势。

In recent years, Metro tunnel detection technology is developing rapidly. Based on the object of our country urban rail tunnel disease detection technology in recent years, summarizes the current for different tunnel diseases commonly used detection techniques, as well as adopted by the new detection technology. the new detection technology including sensor detection technology, digital photographic detection technology, laser scanning technology and multi-functional integrated tunnel checkout automobile technology. This paper introduces in detail the principle of several kinds of new technology, compared the several testing technology (detecting disease type) and the applicable scope of the adaptable conditions, frequency of testing, processing speed, cost, artificial dependence on all aspects of advantage and disadvantage, and analyzes the future development trend (real time, the development trend of integrated automation)of the metro tunnel detection technology.
