Abstract

Slope Mass Rating (SMR) quantifies the adjustment factors of Rock Mass Rating (RMR) for cut slope stability evaluation. However, the discontinuities surface roughness in spite of being a fundamental parameter influencing the peak friction angles (αp) of discontinuities is not considered. Therefore, a systematic cut rock slope stability evaluation proposed here is based on the use of αp of discontinuities and together with the results of SMR classification. The potential for slope failure can be summarised as follows: if SMR predicts failure and dip angle of discontinuity (βi) <αp, the slope has a very high failure potential; if SMR predicts failure and βi > αp, the slope has intermediate failure potential; if stable according to SMR and βip, the slope has low failure potential and if stable according to SMR and βi > αp, the slope is stable. This approach has an additional advantage since the joint roughness determination using tilt testing is relative low cost and does not require complicated testing methods. .
