EQUIVALENT GEOLOGICAL STRENGTH INDEX (GSI) APPROACH WITH APPLICATION TO ROCK MASS SLOPE STABILITY
Rudarsko-geološko-naftni Zbornik, 2022 A considerable amount of slope stability analysis has been observed in jointed rock masses in which the GSI (Geological Strength Index) estimated at the outcropping level is considered input data to define the rock mass strength.
