ABSTRACT
The productivity of TBM tunneling can be determined by its advance rate, proper maintenance, material and equipment logistics, workmanship of operating manpower, etc. Among mentioned factors, the Advance rate is the dominant factor of the TBM performance. This study tried to correlate the Specific Penetration and Field Penetration Index with RMR to figure out the regression between TBM performance and ground condition with TBM operating parameter.
