| 摘 要： | 为了研究加油站便利店火灾的发展规律，选择合理的疏散路线，使用 FDS软件对某加油站便利店进行火灾数值模拟。通过观察烟气扩散和动态升温过程，分析便利店的烟气扩散和升温规律，对比分析不同疏散路线上温度、烟气层高度和能见度的数据变化规律，分析选择不同疏散路线对人员安全疏散的影响。结果表明:在无火灾报警设备的情况下，卫生间等有隔断的设施会延迟设施内人员获得火灾信息的时间,不利于安全疏散；同等高度下靠墙区域受高温烟气影响较中央开阔区域更大；疏散时选择合理的疏散路线可以显著延长安全疏散时间。

| Abstract: | In order to study the development laws of fire in the convenience store of gas station, so as to provide the basis for reasonable selection of evacuation routes, the numerical simulation was carried out on the fire in a convenience store of gas station by using FDS (Fire Dynamic Simulation) simulation software. The smoke diffusion and temperature rise laws of the convenience store were analyzed through observing the visual simulation on the processes of smoke diffusion and dynamic temperature rise, and the change laws of temperature, smoke layer height and visibility on different evacuation routes were comparatively analyzed, then the influence of different evacuation routes on the safety evacuation of personnel was analyzed. The results showed that the partitioned facilities such as toilet would delay the time for the personnel in the facilities to obtain the fire information in case of without the fire alarm equipments, which was adverse to the safety evacuation. The area near the wall was more affected by the high temperature smoke than the central open area under the same height. The reasonable choice of the evacuation route could significantly extend the safety evacuation time. |
