摘要
为实现地铁车厢发生火灾时乘客安全疏散,采用PyroSim分析了地铁车厢发生火灾时机械送排风及挡烟装置对车厢火灾烟气蔓延的影响,分析得出:车厢衔接位置发生火灾时,稳定的机械送排风或挡烟装置能够增加安全疏散时间,保证人员从车厢内向站厅层安全疏散撤离。机械送排风装置与挡烟装置配合使用,可实现短时间内有效控制站内烟气蔓延的目的。
In order to guarantee the safety of evacuation passengers in a subway car when it fires,used PyroSim to analyze the influence of the mechanical supply and exhaust and smoke screen device for spread of the fire smoke when the subway car fires.Analysis concluded that when the central position of car fires,stable mechanical supply and exhaust or block breathing apparatus can increase the safety evacuation time,ensuring personnel's safe evacuation from the car to the station hall.Combining the mechanical supply and exhaust means with block breathing apparatus,the purpose can be achieved that effectively control station smoke spread within a short period of time.
