Abstract: PURPOSE: A pressure release duct tunnel system of a 0.25-kilometer twin bore tunnel is provided to ease passengers by reducing ear noises, to economize in construction expenses by reducing the cross sectional area of a tunnel and to improve the speed of a train. CONSTITUTION: The pressure release duct tunnel system of a 0.25-kilometer twin bore tunnel contains 6 pressure release ducts installed on side walls of the twin bore tunnel where a single tunnel is installed adjacently. And the pressure release ducts, which are 2.25 meters in diameter, are installed at 40.87-meter intervals.

Abstract: PURPOSE: Provided are an inclined bank for decreasing micro-pressure wave of a rail tunnel with 0.25Km grade of extension length and a combined hood with a slit cover to greatly reduce the micro- pressure wave generated during a high entering speed of a train into the tunnel and to decrease noise and vibration at an exit side of the tunnel. CONSTITUTION: The hood comprises inclined banks at an entrance and an exit of a rail tunnel having a length of 0.25km. The bank at the entrance has a slope angle of 45 degrees to form the slit cover combined hood with the inclined bank at front side while the other bank at the exit has a slope angle of 15 degrees. The slit cover combined hood has a measured length of 12.6m. The hood further has openings at both side walls of a rectangular main body protruded to receive the entrance. Each of the openings is in a rectangular passing-through form having a cover.
