Penetration rate and thrust per cutter
Abstract
An analysis of seven hard rock tunnelling projects in Norway reported by Barton (1996) considered the ratio of available thrust per cutter (F) and uniaxial compression strength (σ c ) as a potential measure of likely ranges of penetration rates. Since there was a range of rock compression strengths for each project, the ratio σ c /F (MPa/tnf) also had a significant range. Net penetration rates also varied within each project.
