  Unexpected performance and cost factors for hard rock TBM. Analyses of specific cases with the thrust-penetration...

  Abstract: In the common view of tunneling experience, discontinuities are considered with downscaling effects on the mechanical properties of rock mass. The effect of discontinuities in mechanized hard rock excavation is of ambivalent nature. The presence of favorable number and orientation of joints leads in general to a reduced effort for TBM excavation and higher advance rates; where else the same...
