...) developed by Bieniawski (1973, 1976, 1979, 1989) and the Norwegian Geo- technical Institutes Q system (Barton et al. 1974). The RQD system is a measure of joint spacing and is incorporated as part of both the Q and RMR sys- tems. More recently the Geological Strength Index (GSI), which has evolved from the...

The behaviour of the rock mass is affected by the strength of the intact rock...
