トンネル火災を想定した煙中のストレスの実験調査

抄録

In the case of tunnel fires, it is speculated that the psychological factor of evacuees have influences on the evacuation behavior. Nonetheless, the relationship between the psychological factors and the evacuation behavior in tunnel fires has not been clarified. In this study, in order to clarify the impact of psychological stress on evacuation behavior in tunnel fires, we conducted evacuation experiments using a smoke tent, and investigated the heart rate, evacuation speed and blood pressure. As a result, there were 9 subjects’ heart rate increased during the experiment when Cs = 0.5 m^-1 and 0.9 m^-1 before the experiment. The mean heart rate ratio (during/before) of 9 subjects at Cs = 0.9 m^-1, was 0.02 larger than that of Cs = 0.5 m^-1. There were 6 subjects’ blood pressure increased after the experiment in the cases of Cs = 0.5 m^-1 and 0.9 m^-1. Due to blood pressure recovering characteristic after the experiments, there was a difference between the results by Omron and Wahoo Tickr. In all rising group such as the heart rate, systolic blood pressure and diastolic blood pressure at Cs = 0.5 m^-1 and 0.9 m^-1, the maximum evacuation speed was larger and the minimum evacuation speed was smaller than that of the decreasing group.
