地下商业建筑火灾中人的疏散行为研究与设计优化

Studies on Human Behavior in Underground Commercial Building Fire Situation

火灾情况下疏散时间是人员生存的决定因素,因此研究人员在建筑物中的疏散行为及其影响因素具有重要意义。研究采用虚拟现实的方法,构建了地下商业商业建筑虚拟场景,并招募30名被试进行虚拟现实实验以研究其疏散行为。实验结果表明76.7%的参与者在实验开始时发现了紧急疏散标识,并遵循标识指示方向。学习建筑安全疏散相关专业的人员、有真实疏散经历的人员在疏散实验中有更好的表现。根据实验结果提出了基于安全疏散的地下商业建筑优化设计策略。

In the event of a fire, the evacuation time is significant determinants of survival. Therefore, it is of great significance to research evacuation behavior and its influencing factors. In this study, virtual reality was the tool used to construct an experimental space. Then 30 participants engaged in a virtual fire environment to study its evacuation behavior. The results show that 70% of the participants found emergency evacuation signs at the beginning of the experiment and followed the signs. Those who studied building safety evacuation related majors and those who actually had evacuation experience performed better in evacuation experiments. According to the experimental results, the design strategy of underground commercial buildings based on safety evacuation is proposed.
