<p>Rock Quality Designation (RQD), was introduced by Don Deere in the mid-1960s as a means of using diamond core to classify rock for engineering purposes. Subsequently it was incorporated into the Rock Mass Rating and Q-system classification methods which, ...

<p>The Rock Mass Rating (RMR) System was introduced over 40 years ago, and since then has become a worldwide reference, along with the Q system, for design applications involving estimation of rock mass properties and tunnel support. A massive database of ...

Specific correlations developed to predict the Rate of Advance for open TBMs, double-shields and single-shields, using the RME index are presented.

After 35 years of use throughout the tunnelling world, the RMR and Qclassifications have proved themselves on numerous projects. They stillface misconceptions however, as reflected in recent articles in T&amp;TInternational. Here, Nick Barton, of Nick Barton ...

This paper presents the result of comparison between the modulus of deformation obtained from dilatometer tests and the geomechanical quality of the rock mass using the RMR classification and the basic intact rock properties such as uniaxial compressive strength ...

Over 500 case histories were analysed in two years to bring the Rock Mass Excavability (RME) index to fruition and demonstrate its effectiveness on five current projects. It should be emphasised that the RME index does not replace the RMR or Q systems as used ...

<p>This report discusses tunnel design procedures based on various rock mass classification systems. A comparison is made between the tunnel support design based on the classical Terzaghi rcak load method and the support selection based on the RSR Concept, ...
