چکیده

The Q-slope classification system is originally introduced by Barton and Bar (2017) for jointed rock-slope conditions description which is used for engineering judgment to evaluate slope stability. This study is attempted to use the Q-slope empirical classification system for assessment of jointed rock slopes stability in Bonab-Malekan highway project. To this end, 10 jointed slopes are observed in the high-way path which is required to investigate these slope stability conditions. According to the results of the stability analysis and sustainability possess based on Q-slope principle, a main part of the slopes are located in uncertain conditions (5 cases), 4 slopes is classified as stable and 1 slope indicate the failure condition and instability.
