Index developped by Bieniawski, to provide an quantitative estimate of the quality of a rock mass. RMR is equal to the sum of the six following ratings :1. Strength of intact rock rating, 2. RQD rating, 3. Spacing of discontinuities rating, 4. Conditions of dicontinuities rating, 5 . Groundwater condition rating, 6. Adjustment for orientation of discontinuities.

Indice proposé par Bieniawski, permettant de fournir une évaluation quantitative de la qualité d'un massif rocheux. Le RMR est la somme des six notes suivantes :1. Note "résistance de la matrice rocheuse", 2. Note RQD,3. Note "espacement des discontinuités", 4. Note "Conditions des dicontinuités", 5. Note "Conditions hydrauliques", 6. Ajustement selon l'orientation des discontinuités. Bieniawski (1989)
