| 摘 要： | 针对目前地铁上排热风道普遍采用混凝土风道设计，漏风的情况比较普遍，上排热风道进行烟气控制存在一定隐患的问题，提出了地铁轨行区发生火灾时两种不同的烟气控制策略，即纵向排烟和横向排烟策略.利用计算流体力学CFD技术辅助进行轨行区的烟气控制策略分析.提出其对系统设计及乘客安全疏散策略的不同要求，可为城市地铁的防灾减灾设计提供参考.

| Abstract: | The OTE(over tunnel exhaust) duct is normally applied to control smoke at the track area in a subway station when the train catches fire.Concrete is widely adopted as the material for the construction of OTE duct and the wind leakage in the OTE duct usually appears.So,utilizing the OTE duct to control smoke makes a hidden danger.Two different smoke control modes,i.e.,longitudinal and transverse smoke control strategies,were introduced when there is a fire at the track area of subway station.The system design requirements for the two different smoke control modes and the safe evacuation strategies were proposed.Besides,the analysis of smoke control strategies in the light of computational fluid dynamics (CFD) was also briefly presented.The current research can provide theoretical support for the anti-disaster design of a subway station. |
