摘　　要：基于元胞自动机理论,量化确定了吸引力、摩擦力和排斥力的运算规则,且将疏散人员的心理因素和火灾的影响纳入考虑范围,提出了一种新的室内建筑火灾人员疏散模型,并编制了相应的数值仿真计算程序。模拟结果表明,该模型能够较好地模拟发生火灾时的人员疏散现象,并可以找到不利于人员疏散的瓶颈位置。Based on the theory of Cellular Automata （CA）, a new fire evacuation model for indoor buildings was built. The calculation rules of attractive force, friction and repulsive force were quantified, and psychological factor and fire influence were also considered. The corresponding numerical simulation program has been developed. The results showed that the model can simulate the personnel evacuation phenomenon during a fire effectively, and is a very potential powerful tool to find the bot tleneck during a fire evacuation.
