【摘要】 特长公路隧道通风技术研究一直是公路隧道界关注的焦点 ,由于特长公路隧道风流进出口 (竖井或斜井 )多、联络通道多、风道多、风机多等特点 ,因此 ,其运营通风技术复杂。本文结合秦岭终南山 18km特长隧道的实际情况 ,将网络通风理论应用于实际工程中 ,取得了良好的效果更多还原

【Abstract】 The ventilation system of extra?long highway tunnels is one of focal point for expressway tunnel engineering Because there are many ventilating shafts(vertical shafts and inclined shafts)and passageways linking up the two tunnels,with ventilation ducts and ventilators in the extra?long highway tunnels,the ventilation technology of the tunnel is highly complex In this paper,the authors apply network ventilation theory to tunnel engineering in accordance with Qinling Zhongnanshan 18km extra?long tunnels specific conditions,and the practical applications have shown good effect更多还原
