火灾是大型体育场的主要危险因素，火灾伴随着烟气流动和人员疏散路径，为提高大型体育场的生命安全，结合火灾蔓延和人员疏散的模拟技术应运而生。此外，为了降低大型体育场火灾中的人员死亡率，必须根据模拟结果，根据火灾条件下烟气温度、CO浓度和消光系数对人的行为影响规律，设计火灾与疏散人员之间的界面。因此，研究火灾蔓延对生命安全的影响是十分必要的。本文通过对火灾数据的自动阅读，得到了人员疏散模拟过程中步行速度、路线选择和心理状态的动态变化。由于火灾烟气参数的时变，特别是局部堵塞和路径效率的不均匀，效果会发生突变。为大型体育场馆火灾时人员的安全疏散提供了直观、可靠的依据。
Fire is a major danger in the large stadium due to fire accompanied with smoke flow and evacuation path. As a part of an effort to improve the life safety in large stadium, the simulation technology combined with fire spread and evacuation had been developed. Besides that, in order to decrease the rate of people death in the large stadium fire, the interface between fire and the evacuation people must be designed according to simulation results, based on the influence laws to human behavior by smoke temperature, CO concentration and extinction coefficient in fire condition. Therefore, the investigation of effect of fire spread on life safety is needed. In this paper, the dynamic changes of walking speed, route choice and mental state is obtained from automatic reading of fire data during the simulation of evacuation. The effect abruptly changes due to time-varying fire smoke parameters, especially local jamming and uneven efficiency of routes. From the simulation, the visual and tried evidences would be provided for safe evacuation in fire emergency in large stadiums.
