【摘要】 合理的空间布局对地铁车站消防安全具有十分重要的作用,而售票机的布置方位是影响地铁车站火灾烟气特性的一个主要因素。以某城市在建的地铁站站厅层为物理模型,采用FDS软件对售票机在不同位置情况下火灾的烟气流动情况进行模拟分析,通过比较邻近售票机处的疏散出口的温度、烟气浓度以及能见度,提出了售票机和疏散出口之间较为合理的距离,为实际工程提供可参考的依据。更多还原

【Abstract】 Rational spatial distribution plays a significant role on fire safety of underground subway station, while the location of ticket machine is one of the main factors affecting fire feature.Taking a certain underground subway station which is under construction as physical model,this paper carried out simulation analysis on several fire scenarios with the help of software FDS.By comparing the temperature,smoke as well as visibility under the different distance between ticket machine and the escape exit,the appropriate distance between ticket machine and escape exit was attained which could be a reference for practical projects.更多还原
