基于FDS＋EVAC高校宿舍楼火灾疏散模拟仿真研究

The simulation on fire and evacuation of dormitories in university based on FDS + EVAC

以某高校宿舍楼为例,运用FDS+EVAC模拟出与宿舍模型相近的参数进行火灾和人员疏散的仿真研究.将影响人员疏散的关键因素—烟气的浓度及扩散程度作为主要研究对象,研究在不同的火源位置、不同的燃烧速率以及不同的人员位置等情况下人员疏散的效率.通过模拟火灾烟气运动和人员疏散的情况,发现烟气的浓度和扩散程度严重影响了人员疏散的效率,增加能够通过监测烟雾浓度而改变方向的智能指示牌可以提高人员疏散的效率.

Taking the university dormitory for an example, FDS ＋ EVAC was used to simulate the dormitory model with similar parame- ters for fire and evacuation simulation. The key factors affecting the evacuation- the concentration of flue gas and the degree of diffusion were studied. The efficiency of evacuation was also studied under different fire locations, different burning rates and different personnel positions. By simulating the movement of fire smoke and evacuation, it was found that the concentration and diffusion of flue gas seri- ously affected the efficiency of evacuation. The intelligent indicators which could change the direction by monitoring the smoke concen- tration may improve the evacuation efficiency.
