... was introduced 50 years ago by Professor Bieniawski (Bieniawski 1973) and was later updated in 1989 (Bieniawski 1989). From then until today, its intensive use has allowed a relative homogenisation of criteria of a complex problem as the characterisation of rock masses, facilitating communication between...

The following methodology was established to define the parameters: adequacy of the dataset; definition of strength by the Schmidt test; descriptive statistical analysis; definition of the Rock Mass Rating (RMR) proposed by Bieniawski (1989); definition of strength parameters by the Hoek-Brown (2002) criterion...

... geotechnical parameters of rocky massif quality composing the classification systems, Q (Barton, 1974), RMR (Bieniawski, 1989), and GSI (Hoek et al. 2013) are essential for knowledge of geotechnical domains and better geotechnical modeling based on the variety of tools available in geostatistics.

... Abstract The Hoek-Brown strength criterion is the most used tool for rock mass strength estimate. For weak rocks, with UCS in the range of 3 to 15 MPa, this strength criterion using the GSI or RMR 76 (Bieniawski) classification system yields conservative strength parameters, as observed...

However, most of these correlations show limitation mainly when applied to isotropic rocks randomly jointed. This study presents an alternative correlation to RQD calculation, using...

... Abstract The Slope Mass Rating (SMR; Romana, 1985) geomechanics classification was developed as a sequel of Bieniawski's Rock Mass Rating (RMR) system, which was almost impossible to use in slopes due to the extreme range of the correction factors (up to 60 points of a maximum of 100...
