Gsi rock mass classification
The Geological Strength Index (GSI) system, proposed in 1994 by Evert Hoek, is used for the estimation of the rock mass strength and the rock mass deformation modulus. The GSI system concentrates on the description of two factors, rock structure and block surface conditions. The guidelines given by the GSI system are for the estimation of the peak strength parameters of jointed rock masses. There are no guidelines given by the GSI, or by any other s… Webto determine if GSI is applicable to rock materials found in Ohio. To meet this primary objective, a. literature review was conducted, many rock samples were tested in the lab, …
