..., and the latter includes significant uncertainty. GSI (Geological Strength Index) is such a classification system for which a quantification approach has been proposed by Hoek et al., 2013 including both structure and surface quality components. The current study demonstrates a powerful approach for the GSI rock...

Paper Number: ARMA-2016-438
... Abstract: The use of the Geological Strength Index (GSI) has not been commonly used to characterize rocks like Miami Limestone. Since the limestone is jointless, its appearance is like an intact or massive rock and estimate the GSI values could be wrong. This paper proposes a modified GSI...

Paper presented at the 43rd U.S. Rock Mechanics Symposium & 4th U.S. - Canada Rock Mechanics Symposium, June 28–July 1, 2009
Paper Number: ARMA-09-019
... Abstract The Geological Strength Index (GSI) was introduced by Hoek et. at. (1994) as an alternative method to classify rock mass due to difficulties in applying the Bieniawski’s Rock Mass Rating (RMR) to very poor rock masses. The GSI is an important tool to estimate parameters...
