摘要
对洞口间距小,双洞单向公路隧道火灾排烟工况进行研究,通过对不同工况火灾隧道排烟风速及运营隧道通风速度下的火灾烟气流动利用计算流体动力学进行模拟分析,得出了双洞单向隧道排烟风速与通风风速之间的影响关系,并利用该关系对排烟及通风设计进行了优化,有效地减少了非着火隧道的吸入烟气量,确保了运营隧道的空气品质。结果对该类型公路隧道工程排烟通风设计具有一定参考价值。
Analysis the smoke evacuation of double hole one-way tunnel in close space. Simulate several conditions through CFD and get the relationship between smoke evacuation velocity and ventilation velocity. Then optimize the design of smoke evacuation and ventilation and reduce the amount of smoke accessed into the operating tunnel effectively to ensure the air quality in operating tunnel. The results have some reference value for smoke evacuation and ventilation projects in such highway tunnels.
