| Abstract: | Great challenges have been encountered in the construction of Fenghuoshan Tunnel for its chilly climate and plateau condition. The difficulties are how to construct the tunnel without harm to frozen soils; how to use special techniques to adapt to the absence of oxygen in the plateau. A series of techniques have been adopted to overcome these difficulties, the tunnel is sucessfully constructed eventually. |
