... can be converted into equivalent Mohr-Coulomb (MC) parameters by estimating a suitable range of minor principal stresses. The result is a linear failure envelope. On the other hand, the nonlinear HB failure envelope can be applied directly by calculating apparent MC parameters for each point of the HB...

..., the rock engineering community interprets the possibilities of calculating RMR in different ways. In addition, given that SMR is calculated from RMR by adding four correction factors, different interpretations arise. In this work, different cases of rock masses were analysed and both indexes, RMR and SMR...

... ABSTRACT: Blocks of rock are large fragments of the bedrock that have not suffered a strong erosive process and have remained in the soil horizons. They can be oval shaped, or nearly spherical. The calculation for blasting is different, as the volume between these blocks varies, and so does...

... For stability analysis of rock slopes (wedges, plane failure, toppling, etc.), the data chosen for the calculation concerning the spatial orientation of each of the families (dip and dip direction) are decisive. Moreover, the orientation and characteristics of the families influence the stability of a slope...

... of the rock mass. In numerical calculations visco-elastic and visco-plastic material models are used very often to model long-term rock mass behavior. In the present case a linear elastic – ideal plastic material model with a Mohr-Coulomb failure criterion in combination with a creep function was used...
