Excavatability assessment of rock masses using the Geological Strength Index (GSI)

Bulletin of Engineering Geology and the Environment, 2009
In the present study a new classification method for the assessment of ease of excavation of rock masses is proposed, based on the Geological Strength Index and the point load strength of the intact rock. The data originate from excavation sites in Greece in sedimentary and metamorphic rock masses.

Application of Fuzzy Sets to Geological Strength Index (GSI) System Used in Rock Slope

Soils and Rock Instrumentation, Behavior, and Modeling, 2009
The stability assessment of slopes is difficult because characterization of rock masses and determination of their strength involve many uncertainties due to their complex nature. The fuzzy set theory is one of the tools to handle such uncertainties. And the difficulty can be overcome by using the Hoek-Brown empirical failure criterion in conjunction ...
