摘要
为检验重庆市轨道交通防灾系统安全性,利用全尺寸热烟测试(Hot Smoke Test)的方法,在重庆某地下暗挖岛式地铁车站开展不同场景下试验。检测了地铁防灾系统的联动效果和综合安全性能,实验得到了烟气温度,CO_(2)、CO浓度,烟气层高度等重要参数,分析了站台及站厅2种火灾场景下烟气的分布扩散情况。实验数据可供类似暗挖岛式地铁车站的防灾设计参考。
To test the safety of disaster prevention system of a metro station in Chongqing,the full-scale Hot Smoke Test method was used to carry out tests under different scenes at underground island metro station in a place of Chongqing.By the tests,the interconnection of the disaster prevention system and overall safety performance is examined.The data of smoke temperature,the concentration of CO2 and CO are obtained by experiments.The distribution and diffusion of smoke under two fire scenes of the platform and the station hall were analyzed.The experimental data can be used as a reference for disaster prevention design of similar underground island metro station.
