摘要
Abstract
In this paper, using the numerical simulation technology, and using pyrosim software for tunnel medium scale fire simulation whose power is 20MW, by analysising of the simulation results of the spread of ifre smoke lfow, then draw the critical wind speed of this ifre , and under the critical wind speed, analysis of the numerical simulation on temperature, CO concentration distribution, and come to their distribution. Then with the modiifed formula, FED Suffocation model to escape discrimination condition, considering the temperature and CO concentration under the common action of personnel endure limit time relationship,ifnally draw the safety of the personnel escape direction and the maximum security escape time and the fasthset escape area at different locations of the ifre origin downstream after tunnel ifre.关键词
