基于地铁环境模拟(SES)的区间火灾工况通风模式研究

Ventilation Mode Based on SES Software in Interval Fire Conditions

为确定存在折返线的复杂区间在火灾工况下的风机运行模式,采用地铁环境模拟(SES)软件,对此类区间在火灾工况下的风机运行模式进行了模拟,对同一区间不同风机配置情况以及风机串联、并联运行等多种模式的合理性进行了分析。结果表明:将隧道风机设置在折返线端部,发生火灾时依靠相邻车站开启隧道风机即可满足着火点所需风速的要求,并有多种通风排烟模式可以利用。

In order to determine the fan operation mode in case of fire that happened in the complex interval with reverse line, a subway environmental simulations （SES） software is de veloped to simulate the fan operation in fire conditions, and to analyze the rationality of different fan configurations in series operation mode, in parallel operation mode and so on. It is concluded that when the tunnel fans are set at the end of a re verse line, in the case of a fire, together with the tunnel fans at adjacent stations, they could meet the air moving require ments at the fire point, and make use of a variety of ventila tion and smoke extraction modes at the same time.
