| 摘 要： | 采用FDS软件对八达岭地下车站相关隧道段的火灾工况进行三维数值模拟计算,结果是火灾强度为20 MW时隧道段的临界风速为3 m/s;采用一维数值模拟方法研究分析了火灾发生在隧道段不同位置时的通风方案,结果表明:合理的利用竖井内轴流风机,可以最大限度地减少隧道内射流风机的数量。 |
| 关 键 词： | 区间隧道 火灾控制 临界风速 通风方案 |

| Abstract: | By using FDS software,3-D numerical simulations were carried out to investigate the tunnel fires in running tunnel of Badaling underground station.The critical wind velocity of 3m/s was obtained during the tunnel fires with the heat release rate of 20MW.1-D numerical simulations were adopted to research the ventilation option for tunnel fires occurred at different positions of the tunnel.Results indicated that the number of jet fans used in the tunnel can be reduced to maximun extent,in case that the axial ... |
