| 摘 要： | 城市地下快速通道存在较大的坡度,发生火灾事故时在烟流阻力和火灾通风的共同作用下会增加人员的逃生危险.本文使用CFD软件FDS,从坡度与火灾通风风速变化2方面研究了坡度对人员逃生环境的影响,并用性能化防火设计理论分析了其变化规律,以期为城市地下快速通道火灾事故通风系统设计提供指导. |
| 关 键 词： | 城市地下快速通道 性能化防火设计 人员疏散 数值模拟 |

| Abstract: | For the urban underground express tunnel,there exists a big slope.When a fire happens,the risk for the people to evacuate will be increased due to the combined action of smoke flow resistance and fire ventilation.In this paper,using the software of FDS,the influences of slope and ventilation air velocity on the personnel evacuation environment were analyzed.Furthermore,the corresponding variation trends were studied according to the performance-based fire theory.The results could be considered as the design... |
