阐述了影响安全疏散的因素与火灾危险情况来临时间确定的原则和方法,利用FDS火灾模拟软件建立了超市人员安全疏散的评估方法,并运用该方法对某超市进行安全疏散评估。通过FDS场模拟计算得出超市火灾情况下不同场景的模拟计算结果(图),据此得出火灾危险到来的时刻ter为842 s;并与通过Togawa经验公式计算得出的人员疏散到安全地点所需时间进行比较,得出在火场的危险情况来临前,人员能够全部撤离到达安全区域;从而确定超市建筑的消防安全性,并为进一步开展公共聚集场所人群疏散的安全性评估提供了参考和依据。
The principle and method of determining the time of arrival of fire danger factors and the factors influencing safety evacuation were expounded. An evaluation method of safety evacuation of supermarkets was established by FDS fire simulation software, and the safety evacuation evaluation of a supermarket was carried out by using this method. The simulation results of different scenarios in the case of supermarket fires are obtained through FDS field simulation (Figure), and the ter time at which the danger of fire is arrived is 842 s; and the evacuation to a safe place with the personnel calculated by Togawa empirical formula The time needed to be compared to draw a conclusion that all personnel can be evacuated to a safe area before the dangerous situation of the fire field arrives, so as to determine the fire safety of the supermarket building and provide a reference for further carrying out the evacuation safety assessment of public gathering places and in accordance with.
