초록
최근 도심지 차량 정체 해소와 주변환경을 개선하기 위하여 도심지 지하공간을 활용하는 대심도 복층터널 설계 및 시공기술개발 연구가 진행되고 있으며, 네트워크형 복층터널은 단면이 작고, 평지 하부에 시공됨에 따라 입 ‧ 출구의 경사가가파른 특징이 있는 교차로 형태를 가지며 화재발생시 화재연기가 매우 빠르게 전파되어 인명피해 발생이 우려된다. 따라서 본 연구에서는 교차로에 화재연기 확산지연장치를 설치한 경우와 미설치된 경우에 대하여 화재연기 확산지연효과를 분석하였다. 화재연기 확산지연장치를 교차로에 설치하였을 시 화재발생 후 270초까지 화재연기가 지연되었으며, 화재연기 확산지연장치의 차단면적이 커질수록 인명피해 예방에 도움이 될 것으로 분석되었다.

Abstract
Recently, in order to solve the traffic congestion in urban areas and to improve the peripheral environment, research on the design and construction technology development of great depth underground double-deck tunnel is under way by using the underground space in the urban area. The network type double-deck tunnel is in the form of an intersection with a small cross section and a steep slope as per construction at the base of a flatland, so that the fire smoke spreads rapidly in case of fire, which is expected to cause damage of human life. Therefore, this study is analyzed the delay effect of fire smoke diffusion according to the installation and non - installation of delay system for fire smoke diffusion at the intersection. Fire fumes were delayed up to 270 seconds when the delay system for fire smoke diffusion was installed at the intersection and it is analyzed that the greater the operating area of the delay system for fire smoke diffusion, the more preventable the damage of human life of the intersection.
