RECENT EXPERIENCES WITH THE Q-SYSTEM OF TUNNEL SUPPORT DESIGN. The Q-system of rock mass classification and support design is based on a numerical assessment of the rock mass quality using six different parameters.Cited by: 25

For the linguistics formalism, see Q-systems. For the genetic method, see Q-system (genetics).. The Q-system for rock mass classification is developed by Barton, Lien, and Lunde. It expresses the quality of the rock mass in the so-called Q-value, on which are based design and support recommendations for underground excavations.. The Q-value is determined with

The application of the Q-Tunnelling Quality Index to rock mass assessment at Impala Platinum Mine by W. Hartman* and M.F. Handley† Synopsis Publications on hard rock tunnel support design in the South African mining industry have originated primarily from the gold mines during the past 50 years. Little has been published to date

Rock Mass Classification is the process of placing a rock mass into groups or classes on defined relationships (Bieniawski, 1989), and assigning a unique description (or number) to it on the basis ...

Short on the Q-system . The Q-system for rock mass classification, developed at the Norwegian Geotechnical Institute (NGI) in 1974, originally included a little more than 200 tunnel case histories, mainly from Scandinavia (Barton et al., 1974). In 1993 the system was updated to include more than 1000 cases (Grimstad and Barton, 1993).

Developed the Q-system of rock mass characterization in 1973, which now has world-wide application for site characterization and support design for tunnels and large caverns, with more recent links to seismic velocities and deformation moduli and input for numerical modelling at dam sites. Pioneered and developed practical tools in the

FORTY YEARS WITH THE Q-SYSTEM. Publisert av Aslak Ravlo den 27. januar 2016.. As part of the celebration of ‘Forty years with the Q-system’ Nick Barton and Eystein Grimstad were invited by the Norwegian Tunnelling Society (NFF) to give an updated presentation of the Q-system.

Design of tunnel support. ... A combination of NMT and NATM principles applying the Q-based support design system was proposed for a major tunnel in partly soft and partly hard rock.
