A study on the rescue design of passengers for railway tunnel fire accidents by using simulation program

터널 화재발생시 시뮬레이션 프로그램을 통한 승객대피계획

Fire accident in tunnel is one of the most critical railway accidents, together with overturning of train by derailment and train crash. Tunnel structures contribute to minimize the cost and time of transport, but in case of railway fire accident occurring bring serious damages of human life caused by narrowness of shelter, poisonous smoke and high temperature raised at the inside of tunnel. For that reason, at the beginning of plan of tunnel, the optimum design for rescue of passengers is needed. For the detail and most suitable design for rescue of passengers, many tunnel designer substituted simulation program for mock examination by its high cost and effort. In this study, simulation program techniques, such as Fluent and Simulex, are applied for verifying the rescue design of passengers reduced the risk when fire accident occurred at tunnel utilizing of case study for planned railway tunnels shows 1,245m length in Iksan-Sili area.
