摘　　要：随着基础设施建设的不断深入,深埋隧道日益增多。研究深埋隧道围岩稳定性分析与衬砌施工技术是确保隧道安全、经济、高效建设的关键。文章以国外某隧道工程为例,首先分析了深埋隧道围岩稳定性,然后探讨了围岩稳定性的影响因素,主要包括地层岩性及围岩位移,最后详细介绍了隧道衬砌施工技术,包括隧道超前支护及初期支护关键技术,以期为类似深埋隧道建设工程提供一定的参考与借鉴。With the deepening of infrastructure construction,the number of deep-buried tunnels is increasing.Studying the surrounding rock stability analysis and lining construction technology of deep-buried tunnel is the key to ensuing the safe,economical and efficient construction of the tunnel.Taking a tunnel project abroad as an example,this paper first analyzes the surrounding rock stability of deep-buried tunnel,then discusses the influencing factors of surrounding rock stability,mainly including stratum lithology and surrounding rock displacement,and finally introduces the tunnel lining construction technology in detail,including the key technologies of tunnel advance support and initial support,in order to provide some reference for similar deep-buried tunnel construction projects.
