With large section tunnel, there is a case that a TBM (Tunnel Boring Machine) pilot tunnel advanced widening method is executed. A system is developed in which wall surface image is provided from the TBM pilot tunnel as pictorial image, and an extract and data base changed into it, and keyblock continuous analyses of discontinuity are conducted to evaluate the stability of large section tunnel. The system is applied in Tokyo-Nagoya High Way Okabe Tunnel construction. In conclusions, the labor was largely saved than that of the general method, owing to the DB of the surface of the discontinuity by automatic exposure and application image of TBM wall surface and keyblock continuous analysis.
