Using Tunnel Boring Machine Penetration Tests to Quantify

The steady-state penetration rate is limited by TBM design parameters, which define performance limits. The penetration limit is a function of muck conveyance, bucket design, cutter wear and maximum head revolution speed (Frenzel et al., 2012).
