摘要
为研究巷道火灾的蔓延规律,以实际巷道为基础,建立了尺寸为100 m×4 m×3 m的FDS模型,模拟火灾发生时巷道内烟气的运移规律、能见度及温度场的分布情况。结果表明:风速没有达到阻止烟气逆流的临界风速,在火灾发生后烟气很快向上风向逆流;烟气所到之处温度和能见度均远超人员存活的最低要求。
In order to study the propagation law of tunnel fire,we established a FDS model of size 100 m × 4 m × 3 m on the basis of actual tunnel to simulate the law of smoke movement,visibility and temperature distribution in tunnel during fire. The results show that the smoke will soon wind upstream after the fire if the wind speed did not reach the critical wind speed that prevents the smoke from flowing upstream,the temperature and visibility are failed to meet the minimum requirement for the survival of the personnel wherever the smoke goes.
