| 摘 要： | 目前,国内外对采用双洞单向行驶交通形式的隧道通风问题的研究中,大多忽视短距离连续隧道间污染空气窜流的二次污染问题,对隧道通风效率的影响也鲜见报导。以水涧山隧道与石鼓隧道进、出口段以及隧道间空旷区域为分析对象,以CO浓度为依据,采用FLUENT软件对洞口污染空气的扩散及其对下游隧道窜流的影响进行研究,并提出通过修筑通风洞和明洞处设置射流风机减少污气窜流的对策。 |
| 关 键 词： | 窜流 FLUENT 通风洞 射流风机 |

| Abstract: | The flow channeling in the short distance and continuous road tunnels is almost overlooked, domestic and international, in the study of ventilation for tunnels with one-way traffic. Efficiency of the tunnel ventilation are also rare reported, not to mention systematic study on this issue. In view of this, the flow channeling was researched by FLUENT, based on Shuijianshan and Shigu tunnels, and the exit section of tunnel and open area is analyzed by CO. The technical measures, such as constructing ventilation tunnel and setting Jet Fan in opencut tunnel,are suggested. |
