Conventional rock mass classification systems with essential adjustments to account for rock discontinuities are a feasible approach to analyzing rock slope stability. Moreover, back analysis of a failed or failing slope can be used as a reliable method of determining the shear strength parameters of rock joints. In this work, the slope stability of Karoun trench was analyzed and its geomechanical parameters were estimated, focusing on the slope mass rating (SMR) and utilizing the back-analysis method. SMR was employed to evaluate the stability of the trench. Numerical simulations were then carried out using the Universal Distinct Element Code software package in order to perform back analysis, thus allowing the mechanical properties of the rock slope to be predicted. Although simpler methods of determining slope instability may be available, the authors wished to focus purely on the capabilities of the SMR and the back-analysis method. The results indicate that the modified SMR is a reliable method for the primary assessment of rock slope stability and for identifying the critical failure mode. Moreover, sliding on bedding planes is the dominant failure mode, and the properties of the discontinuities play a key role in the instability of the considered rock slope.
