Abstract

This study introduce that we studied optimization and possibility of smoke spread prevention with air-curtain system in undersea tunnel named from Ho-Nam to Jeju line in domestic if a fire break out in train. To verify performance, air-curtain system is installed between rescue station platform and each door of passenger car to provide safety route to evacuator and we studied simulation model of various cases about 15 MW fire severity considering domestic specifications. As a result we verified the fact that CASE1(air jet with 15degree toward passenger car) and CASE 5 (air jet with 15degree toward passenger car and pressure air blast from cross passage) is best Smoke Spread Prevention and less inflow carbon monoxide. Through above results, we expect that air-curtain system is one of the facilities for fire safety and provide us safety platform route in undersea tunnel.

본 연구는 국내에서 계획하고 있는 호남-제주간 초장대 해저터널에서 철도차량의 화재 발생시 구난역 (Rescue Station)에 정차후 대피자의 안전한 대피경로를 확보하고 플랫폼 내부에 연기가 유입되는 것을 방지하기 위해 구난역 플랫폼과 화재열차 사이에 에어커튼 시스템(Air curtain system)을 설치하여, 15MW급 화재연기에 대한 차단성능 및 최적화방안을 도출하기 위해 다양한 시뮬레이션을 수행하였다. 시뮬레이션 결과, 모든 CASE에서 15 MW급 화재강도에 발생되는 연기에서도 효과적인 차연성능을 발휘하였으며, CASE1(화재열차 방향으로 15도 분사)와 CASE5(화재열차 방향으로 15도 분사 + 가압송풍)가 구난역 플랫폼 내부에 CO가스 유입이 가장 적은 것으로 도출하였다. 이러한 결과를 통하여 에어커튼 시스템은 초장대 해저터널 구난역에 화재시 플랫폼에 화재연기가 유입되지 않고 안전한 대피 경로를 확보하여 대피자가 서비스 터널로 안전하게 대피하여 인명피해를 최소화 할 수 있는 방재시설로서 활용되기를 기대한다.
