Experimental Study on the Slit Cover Hood for Reducing the Micro Pressure Waves in High-Speed Train-Tunnel Interfaces

고속철도에서 슬릿커버 완충공의 터널 미기압파 저감성능

Abstract

Purpose of the present is to investigate the food configuration at a tunnel entrance for reducing the micro pressure wave that is generated according to train speed. Two configurations were examined for tunnel of 0.5 km length. The experimental results show that a slit cover hood installed at the entrance of the tunnel reduces the maximum micro pressure wave by 41.2%, and a configuration with a slit cover hood installed at the entrance and a 45$^{\circ}$slanted portal at the exit of the tunnel suppresses it by 47.7%.
