This study aimed at investigating the influence of tunnel length and area, drag coefficient, train velocity on the characteristics of ventilation in railway tunnel. The modified Subway Environment Simulation(SES) computer program has been used to calculate the flow velocity and longitudinal emission concentration with various condition. According to a series of numerical simulation, the influence of various parameter on maximum air flow velocity, purging length and emission concentration are estimated

철도터널에서 오염물질의 거동은 열차의 운행조건 및 터널의 구조 등과 같은 다양한 인자에 의해 영향을 받아 매우 복잡한 양상을 보이게 된다. 본 연구에서는 SES프로그램을 수정하여 해석한 농도계산을 이용하여 철도터널에서 오염물질의 거동특성을 구명하고, 터널의 단면적, 길이 및 열차의 항력계수, 주행속도가 터널의 최대풍속 및 오염농도에 미치는 영향에 대한 분석결과를 제시하였다.
