| 摘 要： | 本文针对北京市CBD地下交通联系隧道的结构特点和通风设计条件,在环形主隧道中设置典型火灾场景,采用数值模拟软件模拟了设定火灾场景下不同排烟工况时的烟气蔓延规律。而后,以临界风速作为主要判断标准,并以有限的烟气蔓延范围为控制要求,确定了该场景的合理烟控方案。 |
| 关 键 词： | 地下交通联系隧道 烟气控制 数值模拟 临界风速 |

| Abstract: | In this paper,based on the configuration characteristics and ventilation design conditions of Beijing CBD urban traffic link tunnel（CBD UTLT）,one typical fire scenario was set in the main tunnel,and smoke flow patterns of designed fire scenario under different smoke exhaust cases were simulated.And then,taking the critical ventilation velocity as a judgment standard,and taking the limited smoke spread in the tunnel as a control requirement,a reasonable smoke control strategy was determined. |
| Keywords: | urban traffic link tunnel smoke control strategy numerical simulation critical ventilation velocity |
