| Abstract: | New Baota Mount Tunnel goes through the layer separating soil and stones, and sandstone and shale interbed in the transverse layer. Its exit is adjacent to existing lines, with a minimum distance 13.8 m. The technologies of tunnel construction near exiting lines and going through soil and stone separating area are introduced in this paper, which can be reference to similar projects. |
