北京地铁1,2号线区间疏散与排烟模式研究

Passenger evacuation and smoke extraction in underground railway Line 1 and Line 2 tunnels in Beijing

介绍了北京地铁1,2号线设备消隐改造工程的项目背景和改造条件,以模拟计算和现场实测为手段检验了既有通风排烟系统的排烟能力。通过分析北京地铁1,2号线区间隧道的特点,提出了增加区间联络通道数量、火灾时列车侧向疏散乘客的疏散和排烟模式。

Presents the background and conditions of equipment safety retrofit for the two lines.Verifies the smoke extraction capacity of the existing ventilation and smoke extraction system by means of simulation and calculation and field test.Analyses the construction characteristics of the underground railway tunnels,presents an evacuation and smoke extraction mode that the quantity of the connecting holes from a tunnel to the adjacent one between two stations are to be increased and passengers escape from the holes in the case of fire.
