Abstract:

The reinforcement technologies for a tunnel under repairing are analyzed by means of ANSYS and PLAXIS. Mining method is adopted to repair the tunnel 3 months after the accident. The repairing is successful and the finite element analysis results are consistent with the actual situation.

Key words: segment, repairing, ANSYS, PLAXIS, tunnel reinforcement
