Abstract

A variety of research projects have been undertaken due to the recent catastrophic tunnel fires throughout the world. Among them, more emphasis was given to full scale and scale model fire experiments, and recently the area of fire resistance of tunnel structures attract more interests. On the contrary to the cases in most of the advanced countries where design standards as well as recommendations have already been announced, no local criteria for design can be found. This paper aims at deriving the fire characteristics appropriate for the assessment criteria of fire resistance of structures in local tunnels through studying the existing fire temperature curves including ISO 834 standard temperature curve, HC curve, RWS curve, ZTV curve and EBA curve.

최근 전세계의 대형화재 사고이후, 터널안전에 관한 많은 연구들이 진행되고 있다. 특히 실물 및 축소모형 실험에 대한 다양한 연구가 진행되면서, 터널구조물에 대한 내화성능에도 많은 관심이 모아지고 있다. 이미 외국에서는 터널구조물의 내화성능에 대한 설계기준이나 권고안이 발표되고 있으나, 아직 국내에는 설계기준으로 마련되지 못하고 있다. 본 연구의 목적은 각 나라별 화재온도 (온도-시간) 곡선, 특히 ISO 834 표준온도곡선, HC곡선, RWS곡선, ZTV곡선, EBA곡선을 분석하여 국내의 도로, 지하철 및 철도터널의 내화성능 평가 기준에 적합한 화재특성을 도출하는데 있다.
