潭峪沟隧道是八达岭高速公路(北京昌平西关环岛至八达岭)的一个区段,该隧道全长3425m,单管3车道同向行驶。由北峒口驶向南峒口,隧道纵坡-2.7％,隧道入口段200m为R=1650m曲线段,其余均为直线段。隧道横断面呈马蹄形状,总宽度13.10m,车道宽度10.50m,车道两侧均设有排水沟和检修人行道。车道最大高度7.30m,限高5,00m,隧道设计交通量按2016年高峰小时交通量4219 pcu计算,车速60km/h。
The Tanyugou Tunnel is a section of the Badaling Expressway (from the Changping Xiguan roundabout to Badaling in Beijing), with a total length of 3425m and three lanes of a single pipe traveling in the same direction. From Beizhikou to Nanxunkou, the longitudinal gradient of the tunnel is -2.7%. The entrance of the tunnel is 200m for the R = 1650m curve segment and the others are straight line segments. The cross section of the tunnel has a horseshoe shape, with a total width of 13.10m and a lane width of 10.50m. Both sides of the lane are provided with drainage ditches and overhaul sidewalks. The maximum height of the lane is 7.30m and the maximum height is 5,00m. The designed traffic volume of the tunnel is calculated according to the peak traffic volume of 4219 pcu in 2016 at a speed of 60km / h.
