秦岭隧道火灾模式下的通风组织试验方案研究

在具有横通道连接的双线公路隧道中 ,当有一条线路发生火灾时 ,救灾过程中需要打开横通道把人群和车辆疏散到另一条线路 ,此时两条隧道内的通风网络发生了改变。为掌握该工况下隧道内温度、压力、烟雾的发展变化规律 ,可建立模型试验进行研究。本文介绍了秦岭终南山特长公路隧道火灾模式下的通风组织试验的试验方案

A Study of Experiment on Ventilation Organization under Fire Mode in Qinling Tunnel

In double line highway tunnel connected with transverse corridors, when a fire occurs in one line, the corridor should be open during rescue for dispersing the people and vehicles into the other line, then the ventilation networks in two lines would change. In order to ascertain the law of development of temperature, pressure and smoke under such condition, a model test was carried out. In this paper, the test on ventilation organization under fire mode in Qinling Zhongnanshan super long highway tunnel was introduced.
