| Abstract: | Generally open TBM is suitable for hard-rock excavation.Collapse,deformation and hang boots insufficient supports easily occur in weak surrounding rock.This paper is based on Lanzhou-Chongqing railway west Qin-ling extra-long tunnel proj ect and introduces the selection of TBM construction requirements for surrounding rock,to adapt the Geological conditions of the construction section,in order to achieve safe,rapid construction purposes. |
