摘　　要：特长隧道的通风竖井在几何形状、结构受力和施工方法等方面与普通的隧道有很大区别,国内外隧道竖井工程相对较少,许多隧道在通风竖井设计与建设中未能取得十分理想的效果。论文介绍玉临高速公路五老山隧道通风竖井设计与反井钻机施工的具体方案。结果表明:反井钻机可运用于长大隧道的通风竖井施工中,并极大地提高了效率,节约了成本。The ventilation shaft of long length tunnel is very different from that of ordinary tunnel in geometric shape,structural stress and construction method.There are relatively few tunnel shaft projects at home and abroad,and many tunnels fail to achieve very ideal results in the design and construction of ventilation shaft.This paper introduces the design of ventilation shaft and the construction scheme of anti-shaft drilling rig in Wulaoshan Tunnel of Yulin Expressway.The results show that the reverse drilling rig can be used in the construction of ventilation shaft of long tunnel,and greatly improve the efficiency and save the cost.
