摘要：

由于高速公路隧道狭长且封闭的管状空间结构形式，一旦发生由交通事故引发的火灾将会对隧道内人员的生命安全构成严重威胁。文章基于FDS 分析不同火灾工况下隧道内的温度、CO 浓度以及能见度变化，利用Pathfinder 软件模拟不同车辆堵塞密度和疏散方向以及疏散人数下人员的疏散逃生过程，分析影响疏散时间的因素。通过研究得到不同工况下烟气扩散的规律，并对人员疏散的安全性进行判断。

Abstract:

Due to the narrow and closed tubular space structure of highway tunnel, once there is a fire caused by traffic accidents, it will pose a serious threat to the safety of people in the tunnel. Based on FDS software,the changes of temperature, CO concentration and visibility in the tunnel under different fire scenarios were analyzed. Pathfinder software was used to simulate the evacuation process under different vehicle congestion density, evacuation direction and evacuation number, and the evacuation time as well as its influencing factors were analyzed. Through the study, the law of smoke diffusion under different fire scenarios is obtained, and the safety of evacuation is judged and evaluated.  

Key words: highway tunnel, smoke diffusion, evacuation, FDS
