摘要： 为研究地铁换乘站高峰期发生火灾时人员疏散情况，以JMS 地铁换乘站为对象，利用Revit 软件建立其建筑信息模型。通过PyroSim 软件对6 种火灾工况进行模拟，以人体耐受温度、CO 浓度和烟气能见度作为安全指标，研究各通行设施失效临界值；增加年龄、性别和速度等行人参数信息，用Pathfinder 软件探讨高峰期行人在各工况下疏散时间、疏散流量和疏散瓶颈情况。结果表明，工况A2 和C2 疏散失败；逃生过程中行人更倾向身边的通行设施，导致忽视最佳路径；个别通行设施出现疏散瓶颈时，部分设施处于空闲状态，存在设施利用率低、效率低的现象，并针对此情况提出优化建议。

Abstract: In order to study the evacuation of people in a subway transfer station fire during peak period, taking JMS subway transfer station as the object, the building information model was established by Revit. Six kinds of fire scenarios were simulated by Pyrosim, and the failure critical values of all passing facilitieswere studied by taking the temperature, CO concentration and smoke visibility as safety indexes. The pedestrian parameters such as age, gender, weight and speed were added. The evacuation time, evacuation flow and evacuation bottleneck were discussed by Pathfinder. The results show that the evacuation fails under scenarios A2 and C2; Pedestrians are more inclined to pass facilities around during the escape process, leading to neglect of the best route; some facilities are idle when the evacuation bottleneck occurs in other passing facilities, which leads to the phenomenon of low utilization rate of facilities and low evacuation efficiency. Finally, optimization suggestions are put forward for the situation.
