Abstract

Domestic road and railroad construction have been increasingly growing and for reasons of mitigating traffic congestion, urban plan and refurbishment project, deeper and longer tunnels have been built. The event of fire is the most fatal accident in a tunnel, and it can be very disastrous with a high possibility. In this study, QRA (Quantitative Risk Analysis) which is one of quantitative risk analysis approaches was applied to tunnel fire safety design and the evaluation of QRA cases and the cost comparison of QRA methods were carried out. In addition analysis of risk reduction effect of tunnel fire safety system was conducted using AHP (Analytic Hierarchy Process) and the priority of major factors that could mitigate the risk in tunnel fire was presented. As a result, significant cost reduction effect could be obtained by incorporating QRA and it is expected to design fire safety system rationally. The priority of fire safety system based on risk mitigation effect by fire safety system considering the cost is in order of water pipe, emergency lighting, evacuation passage and smoke control system.

최근 국내에서는 도로 및 철도 터널의 건설이 꾸준히 증가하고 있으며, 교통체증 해소 및 도시계획 그리고 개량공사 등에 따라 터널이 더 깊은 지하에 위치하거나 장대화되고 있는 추세이다. 이러한 경우 터널 내부사고 중 인명피해에 가장 큰 위험요소인 화재사고가 발생할 경우 대형사고로 이어질 확률이 굉장히 높아진다. 본 연구에서는 정량적 위험도 분석 기법인 QRA(Quantitative Risk Analysis)를 터널에서의 방재설계에 적용하고자 국내 QRA 사례분석을 수행하고, QRA 기법의 적용 유무에 따른 비용 산출을 비교하였다. 그리고 AHP(Analytic Hierachy Process)기법을 사용하여 터널 방재시설의 위험도 저감 효과를 분석하여 터널 화재시 위험도를 낮출 수 있는 중요 인자들에 대한 우선순위를 제시 하였다. 그 결과로부터 QRA가 적용된 사례에서 상당한 비용절감 효과가 나타났으며, 그로 인해 합리적인 방재시설의 설계가 가능할 것으로 판단하였다. 그리고 방재시설별 비용대비 위험도 저감효과를 통한 방재시설 우선순위는 송수관설비, 비상조명, 대피통로, 제연설비의 순으로 분석되었다.
