Abstract: PURPOSE: A resonant type periodic tunnel structure for reducing micro pressure waves in a high-speed railway tunnel is provided to reduce micro pressure waves through the interaction among the mass, rigidity, and internal space volume of a shielding member. CONSTITUTION: A resonant type periodic tunnel structure for reducing micro pressure waves in a high-speed railway tunnel comprises a tunnel wall (20) for forming a tunnel (10) and a reduction unit (30). The reduction unit is connected to the tunnel and is arranged with a shielding member to shield an internal space. Pressure waves generated by trains are reduced through the interaction among rigidity in the mass of the shielding member and rigidity related to the elasticity of air contained in the volume of the internal space. A plurality of reduction units is arranged along the inner circumference of the tunnel wall in the longitudinal direction of the tunnel.

Abstract: PURPOSE: A periodic tunnel structure for reducing micro pressure waves in a high-speed railway tunnel is provided to reduce the environmental impact pressure waves around a tunnel entrance and the pressure in the passengers' ears. CONSTITUTION: A periodic tunnel structure for reducing micro pressure waves in a high-speed railway tunnel comprises a tunnel wall (20) for forming a tunnel (10) and a reduction unit (30). The reduction unit is connected to the tunnel and is formed on the tunnel wall into an uneven shape. The reduction unit reduces the pressure waves generated during the drive of trains by generating the mismatch of impedance through the cross-sectional changes of the tunnel. The reduction unit is formed with opening surfaces (31) towards the center of the tunnel.

Abstract: PURPOSE: A tunnel structure for reducing micro pressure wave in a tunnel is provided to reduce the pressure of the passengers and the impulsive micro pressure wave applied to the environment around a tunnel entrance by effectively reducing the micro pressure wave and pressure wave inside the tunnel. CONSTITUTION: A tunnel structure for reducing micro pressure wave in a tunnel comprises a tunnel wall(20) and a pressure wave reduction module(50). The tunnel wall is formed with a tunnel(10) inside to pass a high-speed train. The pressure wave reduction module is connected to the tunnel. The pressure wave reduction modules are concentrated inside the tunnel wall into various shapes. The pressure wave reduction module comprises a pressure wave reduction box and a pressure wave reduction pipe. The pressure wave reduction box is installed in the tunnel wall. The pressure wave reduction pipe is arranged inside the pressure wave reduction box. The pressure wave reduction pipe is connected to the tunnel by spirally convolving.
