摘要
以多层住宅楼为研究对象,采用FDS分析最不利火灾场景下烟气蔓延速度场、温度场与能见度,得出可用安全疏散时间。采用Pathfinder分析人员疏散过程,得出必需安全疏散时间。分析结果表明,多层住宅楼发生火灾时人员能够安全疏散。中性面以上的人员疏散时受烟囱效应影响的概率较大,需要紧急疏散且在疏散过程中采取必要措施保护呼吸系统。
The flue gas velocity field,temperature field and visibility of multi-layer residential building in the most unsafety scenario were simulated by FDS to calculate the evacuation time.The evacuation process was studied by Pathfinder to get the necessary time for the safety evacuation.Results showed that people would be able to evacuate in the multi-layer buildings when it was on fire.Emergency evacuation and measures to protect the respiratory system should be applied for people above the neutral layer who would more likely be affected by.chimney effect.
