Abstract

In this study, an analytical evaluation of evacuation safety in typical road tunnels was conducted. The Fire Dynamics Simulator (FDS) was employed to perform fire simulations with varying fire sizes to determine the allowable evacuation time in road tunnels. Additionally, evacuation simulations were performed using Pathfinder, considering the width of barrier doors and the spacing of evacuation passageways, to calculate the required evacuation time. A comparison between the allowable and required evacuation times was conducted to assess the impact of fire size, passageway spacing, and barrier door width on tunnel evacuation safety. The results from the fire and evacuation simulations indicated that an increase in fire size and passageway spacing, along with a decrease in door width, resulted in an increase in the number of casualties. Conversely, increasing the barrier door width to more than 1.2meters led to a reduction in casualties as passageway spacing increased.

이 연구에서는 일반적인 도로터널의 피난안전성을 평가하기 위한 해석적 연구를 수행하였다. Fire Dynamics Simulator(FDS)를 활용하여 화재 크기를 변수로 화재시뮬레이션을 수행하였으며, 도로터널의 피난허용시간을 도출하였다. 또한, Pathfinder를 활용하여 피난연결 통로의 간격과 차단문의 폭을 고려한 피난시뮬레이션을 수행하고, 피난요구시간을 산정하였다. 피난허용시간과 피난요구시간을 비교하여 화재 크기, 피난연결통로의 간격, 차단문의 폭에 따른 도로터널의 피난안전성을 평가하였다. 화재 및 피난 시뮬레이션 결과에 따르면 화재 크기와 피난연결통로의 간격이 증가하고 차단문의 폭이 감소할수록 사상자의 수가 증가하였으며, 차단문의 폭이 1.2 m 이상으로 증가하면 피난연결통로 간격이 증가함에 따라 사상자의 수가 감소하였다.
