Settlements during the driving of the tunnel is an important part of excavated tunneling process until the establishment of support and tunnels pre convergences due to the movement of the face into the tunnel. Therefore possible to reduce the amount of ground face to increase the stability of the tunnel. To this end, the face into the fiber columns, jet grout columns, face bolt, etc., can be performed. In this study, the tunnel excavation stage of permanent support with other support systems studied the effect of the face and applying face bolting case studies were evaluated with the use of the stability of the tunnel. The results clearly demonstrated that the effect of the face bolts in the direction that prevents on the ground settlements.
