摘　　要：为了满足交通需要,部分城市隧道比较复杂,由于隧道本就具有一定的封闭性,再加上复杂隧道路段车流量明显较大,而且这种路段通常设有多个风井,导致隧道内气流变化更加复杂,火灾发生率也相对较高,故而对隧道通风排烟系统的通风效果和排烟能力提出了更高要求。基于此,文章首先分析城市隧道火灾主要形成原因与常用通风形式,然后以实际工程案例为参考,探讨城市复杂隧道通风排烟系统的优化设计,研究成果可为相关研究人员提供思路。In order to meet the needs of traffic,some urban tunnels are relatively complex.Due to the inherent closeness of the tunnel,coupled with the significantly larger traffic flow in complex tunnel sections,and the fact that such sections are usually equipped with multiple air shafts,the airflow changes in the tunnel are more complex,and the fire incidence rate is relatively high.Therefore,higher requirements are placed on the ventilation effect and smoke exhaust capacity of the tunnel ventilation and smoke exhaust system.Based on this,this paper first analyzes the main causes of urban tunnel fire and the common ventilation forms,and then discusses the optimization design of ventilation and smoke exhaust system in urban complex tunnels with practical engineering cases as reference.The research results can provide ideas for relevant researchers.
