隧道通风网络及调节

Tunnel Ventilation Network Calculation

根据隧道通风网络的构成及网络中风流流动的基本规律,运用通风网络解算的斯考德 恒斯雷法和风量调节通路计算法,以二郎山和重庆中梁山2条长大公路隧道工程为例进行了网络模拟和调节计算研究.研究表明,分段纵向式通风系统已形成网络,可通过网络的自然分风和按需分风解算,模拟隧道内风流的分配、风机的设置,从而为确定通风调节的位置、大小和方法提供参考.

Based on the structure of a tunnel ventilation network and the principles of airflow in it, simulation computation is done for the ventilation of two long highway tunnels using the ScottHosley method and the ventilation path method to investigate the effects of the placement and adjustment of jet fans. The results show that a long tunnel with longitudinal and sectional ventilation forms a network and its computation can be carried out by natural airflow distribution to determine the site of jet fans, the amount of airflow and the mode of airflow regulation.
