トンネル火災事故時の排煙運転開始のタイミングが人的被害に及ぼす影響

抄録

In the study of tunnel fire safety, we focused on the behavior of evacuees during the first 10 minutes from the start of the fire. This is because the goal is to complete the evacuation within 10 minutes, and after the initial evacuation is completed, the ventilation system shifts to smoke exhaust operation. If there are evacuees who are caught in smoke during evacuation and their evacuation is delayed, the feasibility of smoke exhaust operation has not been examined yet. In this study, we used simulations to examine the effects on human damage caused by the time from the ventilation operation for initial evacuation to the start of smoke exhaust operation.
