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 a university dormitory as an example, this paper simulates the fire and personnel evacuation by using FDS + EVAC to simulate the fire and evacuation of the dormitory model.Considering the concentration of smoke and its degree of diffusion, which are the key factors of personnel evacuation, The efficiency of evacuating personnel under different locations of fire sources, different burning rates and different staffing positions, etc. By simulating the smoke movement and evacuation of fires, it was found that the concentration and spread of flue gas seriously affected the evacuation of personnel Efficiency and the addition of smart signage that can change direction by monitoring smoke concentration can increase the efficiency of evacuation.
