摘　　要：为了评估某二层复式住宅在发生火灾时的人员逃生安全性,设定了火灾场景,首先用Pyro Sim软件对该住宅的各个逃生口温度,烟气浓度以及烟气层高度进行模拟;然后根据相关资料得出人体对烟气浓度,环境温度的承受极限,得出可用疏散时间TASET为70 s;然后用Pathfinder软件对人员的疏散进行模拟,通过观察比较得出必需疏散时间TRSET为27.5 s;结果表明可用疏散时间TASET大于必需疏散时间TRSET。研究结论为,当该二层复式住宅突发设定的火灾时,住宅内人员可以安全逃生。Simulate a double layer residential flue gas flow, personnel evacuation. Results prove that personnel escape, emergency fire, the researchers were able to escape safely. First：Use PyroSim software to simulated the exit temperature of the residence, flue gas concentration and smoke layer height, then According to the relevant information we got the limitation about the flue gas concentration and environment temperature. Thus we got the Available Safety Egress Time . Then use Pathfinder software to simulated the personnel evacuation, then we got the Required Safety Egress Time. At last derive consequences ： simulation results show that, Available Safety Egress Time TASET=70 s, the Required Safety Egress Time TRSET=27.5 s, so that, could demonstrate when this residence breaking out of fire suddenly, researchers were able to escape in time. Conclusion： When this compound floor residential breaking out of fire suddenly, the survival rate of person is very large.
