摘要
以北京地铁13号线东直门站为例,结合车站公共区与区间隧道的防排烟系统设置情况,分别采用CFD三维模拟与一维网络模拟的方法,对火灾时烟气的分布及气流流动状况进行预测分析,说明防排烟系统的可靠性对于保证火灾情况下的安全疏散能力至关重要。
Taking Dongzhimen Station on Beijing Metro Line 13 as an example, authors of the paper adopt CFD three dimensional simulation and one dimensional network simulation respectively to make a predictive analysis on the smoke distribution and air flow during a fire in accordance with the smoke suppression and exhaust system installed in the public area of the station and in the transit tunnels, and point out that the reliability of the smoke suppression and exhaust system is most important to guarantee the capability of passenger evacuation during a fire.
