ground, the tunnel size, and the method and sequence of constructing the tunnel.

It was a road tunnel.
trust in too much paper. In addition, the structural design of tunnels cannot be compared to the structural verification of other engineered structures. The construction of a tunnel has more to it and thankfully most tunnellers appreciate this. On every tunnel construction project, the correct selection of a construction process is a
