某豪华邮轮客舱人员疏散安全性评估

为评估邮轮客舱人员疏散安全性，使用 FDS 模拟客舱层在固定消防设施失效情况下的火灾，通过各监测指标到达临界值的时间确定可用疏散时间。利用 Pathfinder 模拟客舱层的人员疏散，进而对乘客疏散安全性进行评估。提出相应危险工况的改进措施。结果表明：两种疏散场景下人员均有因烟气作用而被困在楼梯间的风险，需要改变着火层以上各层人员的疏散路线。疏散路线改变后，乘客均能在可用安全疏散时间内完成疏散。

Evacuation assessment of cabin occupants inluxury cruise

In order to evaluate the evacuation safety of cruise cabin occupants, FDS is used to simulate the fire conditions of cabin layers while the fixed fire- fighting facilities fails. The Available Safe Egress Time is taken by the time when the monitoring indicators reach the critical value. Pathfinder is used to simulate the evacuation of occupants in the cabin layers, and the safety of occupant evacuation are evaluated.The improved measures of the corresponding dangerous conditions are given. The results show that in the two evacuation scenes, the occupants can be trapped in the stairwells due to the effect of smoke. Optimizing the evacuation route of occupants above the fire layer is necessary. Occupants can complete evacuation within the available safe egress time while the evacuation route is optimized.
