摘要
针对目前国内环形公路隧道的特点,通过全尺寸环形公路隧道实体火灾试验,考察了环形公路隧道发生火灾时采用集中排烟方式的排烟效果,分别对上坡和下坡两种工况进行分析,获得了集中排烟的具体方式和参数,结果证明在环形公路隧道火灾中采用集中排烟方式能够有效控制隧道中的烟气,可为人员安全疏散和火灾救援赢得时间,试验可以为相应环形公路隧道防排烟标准制订提供参考。
Aiming at the features of annular tunnel in China, By full scale fire experiments, the ventilation effect of concentra- tive smoke ventilation in annular tunnel fire were studied. Scenes of upslope and downslope were analyzed, to get the method and parameters of concentrative smoke ventilation. Results showed that the smoke can be managed with the method of concentrative ventilation effectively, which can provide sufficient time for occupant evacuation and firefighting, the conclusions could be used as a reference in the standard development of smoke management of the annular road tunnel.
