摘要
为了获取T型电缆隧道火灾参数,研究隧道内空气温度及火灾烟雾浓度随时间、空间的分布情况,利用FDS软件建立T型电缆隧道模型,对电缆隧道火灾进行全尺寸模拟。通过对模拟实验数据处理和分析,给出了电缆隧道发生火灾时烟气和氧气体积分数以及纵向温度的变化规律,为现实灭火救援以及火灾中逃生提供理论依据。
In order to obtain the T cable tunnel fire parameters on the air temperature inside the tunnel fire and smoke concentration with time and distribution, use FDS, creat the modeling of industry T cable tunnel and carry out the full-size tunnel fire simulation experiment, analyse the experimental data are given in the cable tunnel fire lo find the rule of smoke concentration and oxygen concentration and vertical changes of temperature and provide a theoretical basis of realistic firefighting.
