Abstract

Increased in vehicles and developed subcenter have caused the traffic congestions in the roads. Great depth underground double-deck tunnel has been designed to solve this problem, which is mainly only for the compact cars with low height and small cross section. There is a possibility of the damage for humans in case of fire in the tunnels. Therefore, the study, the delay effect of the fire smoke diffusion in accordance with the tunnel block area for the development of the delay system for fire smoke diffusion as a method of minimum of the damage for humans in case of fire in the tunnels has been analyzed. In case the delay system for fire smoke diffusion runs, the larger block area increased the delay of smoke diffusion up to 600 seconds and it is expected that the larger block, in turn, will increase the reduction efficiency of the damage for humans.

도로는 차량 증가 및 부도심의 발달로 교통 정체가 발생되고 있다. 이를 해결하기 위한 방안으로 대심도 복층터널에 대한 설계가 계획되고 있지만 주로 소형차 전용으로써 터널 높이가 낮고 단면이 작아 화재 발생시 인명피해가 발생될 경우가 높다. 따라서, 본 연구에서는 대심도 복층터널의 화재시 인명피해 발생 최소화 방안으로 화재연기 확산지연설비 개발을 위한 터널 차단면적에 따른 화재연기 확산지연 효과를 분석하였다. 화재연기 확산지연설비 작동시 차단면적이 커질수록 최대 600초까지 화재연기가 지연되었으며, 차단면적이 커질수록 인명피해발생 저감 효과가 커질 것으로 예측되었다.
