摘要
为了研究特长水下隧道侧向排烟系统的排烟效果,以某特长城市水下隧道工程为例,借助FDS软件建立模型。对比有、无纵向风情况下,隧道内不同车道上方烟气层高度及人眼高度处能见度分布。结果表明:侧向排烟模式下,隧道内不同车道烟气分布差异明显,纵向风对排烟系统的排烟效果有明显影响。
In order to study the smoke exhausting effect of the urban special underwater tunnel lateral smoke exhaust system,a special urban underwater tunnel project is taken as an example to establish a model by means of FDS software.Comparing the situation which is there any longitudinal wind,the distribution of the smoke layer height and visibility at the height of the human eye in in different lanes in tunnel.The results show that under the lateral exhaust mode,the smoke distribution in different lanes in the tunnel is obviously different,and the longitudinal wind has a significant influence on the smoke exhausting effect of the exhaust system.
