Abstract
In the case of a medium length road tunnel, the installation of a smoke control facility is not mandatory so users can suffer considerable injuries if a fire breaks out. Therefore, this study analyzed the high-temperature air and toxic gas generated by fire proliferating with time when a smoke barrier is not installed and when the installation interval is 100, 150, 200, and 250 m through 3-dimensional numerical analysis, evacuation simulation, and Quantitative Risk Assessment Methodology targeting the medium length road tunnel. As a result, the diffusion of the high-temperature air and toxic gas occurring from the a fire was delayed when the smoke barrier was installed in a medium length road tunnel compared to that when it was not installed. In addition, when the installation interval of a smoke barrier was 100m and the numerical analysis target was 100m, the diffusion of high-temperature air and toxic gas generated by the fire was delayed more than in the other cases, which was most suitable for tunnel users to evacuate.
