| 摘 要： | 论述可有效分析地铁空气环境的软件SES(Subway Environmentall Simulation),对其中的火源模型进行详细介绍.利用该软件,对北京地铁7号线达官营站-广安门站内区间火灾工况下的不同通风方案进行模拟分析.通过计算结果可知:开启着火区间两端车站隧道风机以及在区间渡线位置增加射流风机,均不能保证区间...

| Abstract: | SES(subway environmental simulation) is effective software to solve subway environment problems.This article gives a detailed introduction of the fire model of SES,based on which a simulation was carried out on the different ventilation options for the tunnel between Daguanying Station and Guanganmengnei Station on Beijing metro Line 7 in which occurred a fire accident.Simulation results indicated that air velocity in the transit tunnel on fire was below 2.0m/s when ventilation fans on two adjacent stations... |
