摘要
广东清远蟠龙隧道选择采用设置双侧检修道的扁平三心圆内轮廓断面,隧道扁平率为0.57,内轮廓断面比较扁平。隧道断面具有断面利用率高、结构受力均匀、合理的优点。介绍了蟠龙隧道的设计,可作为其他类似项目设计的参考。
The Qingyuan Panlong Tunnel adopts a flattened three-centred inner contour cross section with double maintenance paths.The flattening rate of the tunnel reaches 0.57,with a quite flattened inner contour cross section.The cross section of this tunnel has such advantages as high coefficient of utilization,even and reasonable structural stressing.The design of Panlong Tunnel has been introduced,which could be used as references for design of other similar projects.
