地铁过江隧道火灾烟气控制及疏散设计

Smoke control and evacuation design of subway tunnel under yangtze river

以某地铁过江隧道为研究对象,分析长大区间在火灾烟气控制及安全疏散方面的设计难点,对隧道横断面、疏散路径、通风系统等提出设计方案,通过设定相应的火灾场景及疏散场景,对火灾特性、烟气蔓延、人员疏散等进行模拟,探讨火灾烟气控制及安全疏散设计方案的可行性。

Taking a subway tunnel under yangtze river as example,difficulties in smoke control and safety evacuation design of long-distance tunnel,design on cross-section,evacuation route and air condition system was analyzed.Fire scene and evacuation scene was set,fire characteristic,smoke spread and people evacuation were simulated,the feasibility of smoke control and safety evacuation was discussed.
