Abstract：Research purposes: The construction of Guancen Mountain Tunnel was a key controlled project for Shuozhou -Zhungcer Railway to cross Guancen Mountain. The tunnel was limited by topography and not suitable to adapt inclined shaft. The research on the adaptability of open-type TBM in the tunnel was done.
Research methods: With condition of geology, length, section，ground and organizing traffic, this paper studied the adaptability of TBM, constructing scheme，constructing time limit for project and constructing risks.
Research results : Guancen Mountain Tunnel has conditions to use open-type TBM.
Research conclusions:(1)The open-type T13M can adapt the construction of Guancen Mountain Tunnel.(2 ) The Guancen Mountain Tunnel may adopt the scheme that TBM was installed in outside of the tunnel，used mine construction in soft rock sector, walked into tunnel to dig or that TBM was installed into the tunnel and dig directly, used mine construction in soft rock sector.(3)The constructing least time limit for the project is 42. 5 months to adopt open-type TBM in Guancen Mountain Tunnel(4)The Guancw Mountain Tunnel can adopt open-type TBM to construct，but there are some constructing risks
