It was shown that the 3D deformation in the tunnel at soft rock was obvious at F7 fault and phyllite section, with the characteristics of large deformation and longitudinal displacement developing in the opposite direction of work face and being stable at a distance about 2.0 times of tunnel diameter from the work face. And the 3D displacement of tunnels at F7 fault zone developed in an uneven symmetrical way, while there was good consistency for 3D deformation at slate section. Furthermore, there was a mutally verifying relationship between 3D deformation and ground stress distribution of tunnel region.
