隧道施工射流通风中横通道的风流控制

CONTROL OF AIR FLOW PASSING THROUGH CROSS TUNNELS FOR JET VENTILATION IN TUNNEL CONSTRUCTION

本文详细介绍了隧道施工射流通风中利用射流风机对横通道风流进行调压控制的方式以及各种方式的风量计算方法 ,并结合具体算例对各种方式的能耗进行了分析比较 ,从中得出一种最节能的调节方式。

This paper provides a detailed description of methods on control of air flow passing through cross tunnels and the calculation of air volume rate of jet ventilation in tunnel construction. With ventilation case, this paper also makes analysis and comparison on the energy consumption rate of different methods, by which a most economical method is selected.
