  1. Slope Mass Rating (SMR) • Chinese Slope Mass Rating System (CSMR) • Rock slope rating (RSR) • Slope stability rating (SSR) classification system • Dump mass rating Classification systems in slope stability analysis

  2. SMR = RMR + (F1 .F2 . F3) + F4 The RMR is computed according to Bieniawski’s 1979 proposal,adding rating values for five parameters: • Strength of intact rock; • RQD (measured or estimated); • Spacing of discontinuities; • Condition of discontinuities; and • Water inflow through discontinuities Slope Mass Rating (SMR)

  3. F3 reflects the relationship between the slope face and the joint dip. F4 is a factor for the method of excavation. The adjustment factor for the method of excavation has been fixed empirically as follows: • Adjustment ratings for method of excavation (after Romana, 1995)

  4. Rock slope rating (RSR)

  5. Slope stability rating (SSR) classification system
