Abstract

The present article provides an empirical relationship for rock slope stability assessment based on Qslope classification. The relationship is used as a correction procedure for classic Qslope for mountain regions with multiple fractures related to several faults. The relationship is derived from 25 distinct jointed slopes near the North Tabriz Fault (NTF). The NTF triggered numerous micro-faults and fractures in rocky landscapes, resulting in sliding on a variety of scales. The present empirical method is introduced based on a field survey and a stability analysis of the studied slopes based on Qslope principles. The results indicate that the classic formulation of Qslope can be modified to β = 62.6 log10 (Qslope) + 36 for mountain regions with multiple fault zones. • This empirical method can be useful for fast stability assessment on jointed rock slopes. • This relationship can use as a modification for the original formula in multiple faults zones.
