The presented article provides an empirical method on rock slope classification, slope mass rating (SMR), Qslope, stability condition, failure type and stabilisation procedures for 35 road/railway discontinuous rock slopes after field surveys in Isfahan Province of Iran. Also, it presents the empirical correlation for SMR and Qslope classification system that prepares a link between the stability status (safety factor, reliability condition) and stabilisations (failure mechanism, support system) which performed on natural/trench slopes cases related sedimentary rocks cuts in the studied region. As results, the SMR-Qslope equation for Isfahan Province obtained as SMR = 11.89 ln(Qslope) + 71.92 (R2 = 0.756). • This method can be useful on a stability assessment and providing appropriate stabilisations for the discontinuous rock slope based on simple assumptions where used in different geotechnical projects such as road/railway slope, excavations, open-pit mining, trench boring, etc. • This method can be useful for quick calculation of stability conditions and suggestion of slope maintenance system in a short time as preliminary reactions. • This method can be used as an effective way to convert SMR and Qslope equations and used both benefits in geo-engineering application faced with discontinuous rock masses. • This method can be useful for future research on the empirical geomechanically classification and rock mass preliminary quantifications. • This method can be used as an appropriate database for SMR and Qslope classification.
