【摘要】 从轨道交通隧道火灾场景特点出发,通过数值分析和全比例烟气试验,探讨了列车运动过程中着火及运动至停车过程中烟气的迁移规律。针对不同烟气发展阶段提出通风控制方式,剖析了现行烟气控制模式的有效性,提出了全新的区间隧道烟气控制理念。更多还原

【Abstract】 Based on the characteristics of fire scenario of rail transit tunnel,smoke propagation regulation during the period from a running train catching fire to train stopping in running tunnel is studied through simulation prediction and full-scale smoke test.Ventilation control modes are proposed regarding to different smoke development stages in the whole process.Effective analysis is made to the current smoke control mode and a new concept of interval tunnel smoke control is proposed.更多还原
