| Abstract: | 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. |

| Keywords: | tunnel inner contour three-centred flattening rate |
