... RMR (Rock Mass Rating) by BIENIAWSKI .(1973) 'is very w~ll known and sis- ternatically'applied in tunnels and'dam foundations. The use of this classification in slopes poses many problems due to tile difficulties in stablishing the correction factors for slopes proposed by BIENIAWSKI. SMR (Slope Mass...

... criterion. An approach to the assessment of rock mass deformability, which uses a modified empirical correlation with Rock Mass Rating (RMR) and which takes account of intact rock modulus, is also outlined.

.... The classification is based on six parameters: the uniaxial compressive strength of the rock material, drill core quality RQD, spacing, orientation and condition of discontinuities and groundwater con- ditions. Importance ratings are allocated to each parameter and total rock mass ratings (RMR) for five rock mass...
