The results show that for the single-track shield tunnel in actual projects,the longitudinal ventilation velocity of 2.6~2.9 m/s can effectively prevent smoke from counter flow at a heat release rate of 10 MW;when the tunnel sector on fire with a longitudinal velocity of 2.9 m/s and the unfired tunnel sector with the velocity of 1~1.5 m/s from both ends,there is an air flow with the velocity of 6 m/s ...

模拟分析得出，对于地铁实际工程中的单线盾构圆形隧道，在10 MW火灾强度下，着火区间隧道内2.6~2.9 m/s左右的纵向风速可以有效阻止烟气发生逆流；在着火区间隧道2.9 m/s的纵向风速下，未着火区间隧道两端对送送风速度为1~1.5 m/s时，联络通道内有风速为6 m/s左右的气流流向着火区间隧道，可有效抑制烟气通过联络通道向未着火区间隧道蔓延，保证人员的安全疏散。
