摘　　要：以湖南省某公路山岭隧道断层大塌方处理为例,结合目前隧道塌方处理的典型案例进行分析,总结出了一种更适合隧道断层大塌方处理的施工技术.通过在该山岭隧道断层大塌方处理的实践证明,该施工技术不但能很好地满足施工速度、经济效益、可操作性及施工安全等方面的要求,而且在施工过程中还能保证塌方处理不受塌穴内二次塌方的影响,能有效避免二次灾害的发生.Taking a highway mountain tunnel in Hunan Province as the research object, a construction technology which is more suitable for large tunnel fault collapse treatment is summarized by combining with the analysis of current tunnel collapse treatment of typical cases. Through the practice, it is proved that the construction technology can not only meet the requirements of construction speed, economic benefit, operability, and construction safety, but also can ensure that the collapse treatment is not affected by the secondary collapse in the cave, and can effectively avoid the occurrence of secondary disasters.
