中文摘要：

阐述了翔安隧道左线进行的热烟测试，包括试验方法、工况设置、测量数据的确定与分析，试验同时采用了甲醇和汽油两种燃料。试验发现，火灾初期烟流速度较小，翔安隧道采用的分段纵向排烟方式可以有效控制烟气扩散，为了保证人员疏散安全，隧道风机系统应按照火情发展合理组织运行。

英文摘要：

Hot smoke tests carried out in the left line of Xiangan tunnel, including the research method selecting, conditions setting, and measured data collation and analyzing were described. Petrol and methanol hoth were used as fuel in the smoke tests. The test indicates that at the initial fire, the speed of smoke movement is slow and it can be effectively controlled by the tunnel ventilation and smoke extraction system. The operation method of the fans should be carefully considered with thedevelopment of fire in tunnel.
