| 摘 要： | 采用CFD方法监测了上海地铁一号线人民广场站站台火灾环境下,采用事故风机+站台空调通风与回风+站台下侧排烟的强制通风、不同屏蔽门开启方式对烟气温度场、CO分布及浓度的影响.结果表明:着火6 min时,强制通风可使站台楼梯口温度Tavg<50.73℃,CO]avg<150 ppm,并基本消除CO由站台层向站厅层的扩散;部分开启屏蔽门可实现站台层烟气向站台隧道的抽吸,增加站台安全撤离区域.结果同时指出站台层至站厅层个别楼梯口的温度、风速及风向尚未完全达到地铁设计规范要求,需要进一步分析原因.

| Abstract: | For inspecting plans of extract smoke to secure people's evacuation under the circumstance of fire,CFD was applied to supervise the fire environment on people's square island-platform station of Shanghai Metro line 1,and focused on the influences of widely used forced wind system(tunnel ventilation fan(TVF)+air conditioning of platform(SEF)+under platform exhaust(UPE) on smoke temperature and CO distribution and concentration in the range of platform and on the entrance of stairs,the key routes for evacuati... |
