<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 ...

<p>For professional tunnel engineers, for whom money and time are in short supply particularly in early stages of a project, this paper critically assesses what works best with the RMR system, today 40 years after its development and extensive accumulated ...

In this work Data Mining tools are used to develop new and innovative models for the estimation of the rock deformation modulus and the Rock Mass Rating (RMR). A database published by Chun et al. (2008) was used to develop these models. The parameters of ...

Current approaches to rockfall hazard and risk mitigation have been dominated by a model in which rockfall is treated as a global slope stability phenomenon which is mainly triggered by precipitation, freeze-thaw, or root wedging. The methods implemented by ...

The main rockmass classification systems make use of similar rockmass parameters. It is therefore shown how the input parameters of the RMR, Q and RMi systems can be combined into one set of tables. These enable the ground quality to be found directly and ...

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 ...
