.... 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...

These systems were proposed by several researches and the geomechanical classifications most used by the geotechnical community are Rock Quality Designation (Deere et al., 1967), Rock Mass Rating (Bieniawski, 1989) and Q-System (Barton et al., 1974). Rock...

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 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...

... 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...
