Abstract

As we learned in Daegu subway fire accident, fire in the railway tunnel is prone to develop to large disaster due to the limitation of smoke control and smoke exhaust. In railway tunnel, in order to ensure fire safety, fire prevention and fighting systems are installed by quantitative risk assessment results. Therefore, in this research, developed the program to establish quantitative risk assessment and suggested quantitative safety assessment method including fire scenarios in railway tunnel, fire and evacuation analysis model, fatality estimate model and societal risk criteria. Moreover, this method applys to plan preventing disaster for Honam high speed railway tunnel. As results, we presented the proper distance of escape route and societal risk criteria.

대구지하철 화재사고에서와 같이 철도터널 내 화재는 제연과 배연의 어려움으로 자칫 대형 사고로 이어질 가능성이 크다. 철도터널에서는 화재 시 안전성 확보를 위하여 정량적 위험도 평가를 통하여 방재 시설을 설치하도록 되어 있다. 이 연구에서는 터널내 화재시 정량적 위험도평가를 위해서 필요한 화재발생 표준시나리오, 화재 및 대피해석모델, 사망자 추정모델, 사회적 위험도 평가기준 등을 정립하여 철도터널에 대한 정량적 안전성 평가 기법을 제시하고자 하였다. 또한 본 연구에는 각각의 철도터널 화재사고에 대한 정량적 위험도를 평가할 수 있는 프로그램의 개발과 각종 모델을 정립하여 호남고속철도 방재시설 설계에 반영하였다.
