摘　　要：利用FDS模拟教室火灾,分析有无水喷淋和不同通风口开启个数对火场CO生成量、氧含量等参数的影响。利用人员疏散的经验公式计算了该教室的所需安全疏散时间,依据FDS的计算结果分析tRSET和tASET是否满足安全疏散要求,最后与人员疏散二维元胞自动机随机模型的计算结果进行了对比和分析,并为教室安全疏散管理提出建议。FDS was used to simulate the classroom fire process.Several parameters,such as concentration of CO and O 2,were analyzed under the different conditions of fire sprinkler system and ventilation state.Experiential formulas on occupant evacuation were used to calculate the required safety egress time.Then,t RSET and t ASET were analyzed based on the results of FDS simulation.A 2DCellular Automaton random model was also used to simulation the evacuation process and was contrasted with the results from experiential formulas.A piece of advice on evacuation management was put forward based on the above.
