公路隧道通风网络理论的研究及应用

Study and Application of Highway Tunnel Ventilation Network Theory

主要讨论了通风网络理论及其在公路隧道通风中的应用。推导出交通通风力在通风网络理论中的计算公式,介绍了风机、自然风等各压力源在通风网络中的处理办法。应用隧道通风网络解算程序,对雪峰山隧道的通风方案进行计算分析,取得了良好的工程效果。

Ventilation network theory and its application in the ventilation of highway tunnels are discussed in the paper. The calculation formula for the ventilation pressure of the traffic air in the ventilation network theory is deducted. The treatment methods for the ventilation fan air, natural air and airs with other pressure sources in the ventilation network are presented. Calculation analysis is made on the ventilation scheme of Xuefengshan tunnel by means of the calculating program of the highway tunnel ventilation network and good engineering results have been achieved.
