| 摘 要： | 成都南部地铁区间隧道采用地面开口的自然通风模式,在国内尚属首次。文章对区间隧道在火灾工况下,通风竖井间距、隧道中隔墙,以及风口阻力系数对自然排烟通风效果的影响进行了数值模拟分析,为区间隧道的结构选型提供了科学的依据。

| Abstract: | Natural ventilation through shafts from ground surface to the transit tunnels in the southern part of Chengdu metro is employed for the first time in China.This paper gives a detailed introduction to the numerical analyses of the effects on smoke exhaust for the transit tunnels during a fire with respect to the spacing between ventilation shafts,the intermediate wall of the tunnel and the coefficient of resistance of air flow at ventilation openings. It provides a scientific basis for the arrangement of ventilation shafts and the structural type selection of transit tunnels. |
