Abstract :
The tunnel is already an important component in traffic construction. We mainly use new Austrian tunneling method to design tunnel, and it aimed at "timely support" timely feedback measurement data required to determine reasonable supporting time [1]. Due to the tunnel construction in a closed working space, geological complex and changeable, only through the engineering analogy method to guide the designing and construction of the tunnel, it is difficult to meet the practical situation. International started to use numerical calculation to simulate tunnel construction design to determine the stability of the tunnel.
