摘要
本文针对奥体南区地下环形隧道防排烟系统设计,采用FDS模拟及现场热烟试验研究在防烟分区FY-3内发生汽车火灾时,隧道内烟气蔓延、能见度、重点位置温度场变化情况。模拟结果和热烟试验效果基本一致,在排烟风机及时开启联动排烟的工况下,烟气基本被控制在防烟分区FY-3内,人员疏散路径上未出现大面积烟气沉降现象,控烟排烟效果明显。
This paper analyzes the design of smoke control and exhaust system of underground ring tunnel in the southern area of Olympic Sports.FDS simulation and field hot smoke test were used to study the smoke spread,visibility and temperature field changes in key positions in the tunnel when an automobile fire occurred in FY-3.The simulation results are basically consistent with the results of hot smoke test.Under the condition that the smoke exhaust fan is opened in time for linkage smoke exhaust,the smoke is basically controlled within the fY-3 smoke prevention zone.There was no large area of flue gas settlement on the evacuation path.The effect of smoke control and exhaust is obvious.
