Abstract

In this study, we investigated the operation of railroad fire fighting vehicles against fires on trains in a long railway tunnel. In recent years, long railway tunnels (more than 10 km in length) have been built and the number of such tunnels, such as the Geumjeong tunnel (20.3 km in length) on the Gyeongbu high speed line, Solan tunnel (16.7 km in length) on the Yeongdong line and Yulhyeon tunnel (50.3 km in length) on the Suseo high speed line which is scheduled to be opened in the second half of 2016, is increasing. Significant damage is to be expected, due to the increased evacuation time and limited accessibility of fire services when the train is stopped by an urgent fire in the tunnel. Special fire fighting vehicles capable of running on rails have been developed and operated in overseas advanced countries. Therefore, a fire-response system using Unimog vehicles, which can run on road and rail, instead of road vehicles, is necessary. The characteristics of the railway tunnel and thermal environmental change caused by a train fire in a tunnel were analyzed in this study. Also, the operational requirements of the railroad fire fighting vehicles were evaluated by taking into account the specifications of the railroad fire fighting vehicles under development.

본 연구에서는 장대터널의 철도차량 화재사고 진압을 위한 소방차량 운용 시 고려사항을 분석 및 검토하였다. 최근들어 터널연장 10 km 이상의 긴 장대터널 시공사례가 늘고 있으며 경부선의 금정터널(연장 20.3 km)을 시작으로 영동선의 솔안터널(연장 16.7 km) 및 2016년 하반기 개통 예정인 수서고속선의 율현터널(연장 50.3 km)까지 점점 터널의 길이가 증가하는 추세이다. 이에 따라 터널 내에서 철도차량 내 대형화재사고 발생으로 긴급정차 시에 승객의 피난시간이 길어지는데 반해 소방인력의 접근은 더욱 어려워져서 큰 인명피해의 발생이 우려된다. 이에 해외 선진국에서는 철도선로 주행이 가능한 특수소방차량을 개발 및 도입하여 운용 중에 있다. 따라서 국내에서도 기존 도로전용 소방차량이 아닌 철도터널 내에서 운행이 가능한 특수소방차량 도입을 통한 대응체계 구축이 요구된다. 상기 목적으로 본 연구에서는 철도터널의 주요 환경과 철도차량 내 화재발생에 따른 터널 내 열환경 변화를 분석하였다. 또한, 분석결과를 개발 중인 장대터널용 소방차량의 주요 사양과 연계하여 국내 장대철도터널에서 소방차량 운용 시 주요 고려사항을 제안하였다.
