摘　　要：以某高校某教学楼为研究对象,在现场观测数据的基础上,运用PyroSim和Pathfinder软件进行火灾数值仿真模拟,研究教学楼出口处烟气能见度、环境温度的变化规律对人员疏散的影响,根据疏散结果进行安全性判定,并基于系统动力学原理,提出合理的SD安全对策模型。研究结果表明,优化必要的安全出口,可有效提高疏散效率,疏散总时间缩短了132.5 s;增设必要的自动喷水灭火系统、机械排烟系统,在火灾发生300 s时,出口温度降低,烟气能见度提高了约20 m,可大大提高出口的逃生安全性。This paper takes a teaching building of a university as the research object,on the basis of on-site observation data,uses PyroSim and Pathfinder software to carry out numerical simulation of fire,to study the influence of the change rule of smoke visibility and ambient temperature at the exit of the teaching building on the evacuation of the personnel,and to make a safety judgement according to the evacuation result,and based on the principle of system dynamics,puts forward a reasonable SD safety countermeasure model.The research results show that optimizing the necessary safety exits can effectively improve the evacuation efficiency,and the total evacuation time is shortened by 132.5 s;Adding the necessary automatic sprinkler system and mechanical smoke exhaust system,300 s after the fire occurs,the exit temperature is reduced,and the smoke visibility is increased by about 20 m,which can greatly improve the escape safety of the exit.
