摘　　要：以位于湖南省怀化市的界牌隧道工程为例,分析了隧道塌方的原因,提出了隧道塌方的处治措施,重点阐述了护拱法处治隧道塌方影响段及塌方的注浆加固、护拱施工的关键施工技术。经过实践得出结论:采取合适的措施处理隧道穿越复杂地层施工中的塌方至关重要。在界牌隧道工程中,塌方处治效果良好,证明了治理措施的可行性。Taking the Jiepai Tunnel project located in Huaihua City,Hu'nan Province as an example,the paper analyzes the reasons for tunnel collapse,proposes treatment measures for tunnel collapse.It focuses on the key construction techniques of using arch protection method to treat the affected section oftunnel collapsegrouting reinforcement,and arch protection construction.Through practice,it has been concluded that it is crucial to take appropriate measures to deal with the occurrence of tunnel collapse during construction when tunnels pass through complex strata.In the Jiepai Tunnel project,the landslide treatment effect was good,which proves thefeasibility ofthe treatment measures.
