| 中文摘要: |
| 以单元式高层住宅建筑为研究对象，本文应用FDS软件对其火灾烟气特性进行数值模拟计算，得到了单元式高层住宅建筑火灾烟气蔓延速率、可见度、有害气体浓度、火场温度等火灾烟气特性变化规律。计算结果表明：火灾发生60s时，火场环境适宜人员疏散逃生；360s时，火灾烟气对人员疏散逃生造成威胁。数值模拟结果可为单元式高层住宅建筑防火设计及人员疏散逃生方案提供理论参考。 |
| 英文摘要: |
| Objected to unit-divided high-rise residential building, the FDS software has been applied to numerical simulation of fire characters. The variations of fire characteristic parameters such as fire smoke spread flow characteristics, visibility, concentration of toxic gases and fire temperature in the unit-divided high-rise residential building have been obtained. The results show that the fire environment is suitable for the personnel evacuation within 60s while the fire smoke poses a threat to the crowd evacuation after 60s and before 360s.The numerical simulation results can provide theoretical reference for the fire protection design and personnel evacuation design of the unit-divided high-rise residential buildin |
