PURPOSE: A tunnel construction method using a reinforcing wall is provided to increase stability by decreasing ground settlement, crown displacement, convergence displacement, face displacement and support stress. CONSTITUTION: A tunnel construction method using a reinforcing wall is as follows. A plurality of reinforcing walls(100) are formed on both sides of a tunnel excavated. The reinforcing wall supports the load of upper ground of the tunnel excavated. A loop of the tunnel is formed between the reinforcing walls. The loop of the tunnel is connected to the reinforcing wall. The inside of the tunnel is finished. |
