Excavatability assessment of rock masses using the Geological Strength Index (GSI)
Bulletin of Engineering Geology and the Environment, 2009In 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.

Evaluating Variability and Uncertainty of Geological Strength Index at a Specific Site
Rock Mechanics and Rock Engineering, 2016Geological Strength Index (GSI) is an important parameter for estimating rock mass properties. GSI can be estimated from quantitative GSI chart, as an alternative to the direct observational method which requires vast geological experience of rock. GSI chart was developed from past observations and engineering experience, with either empiricism or some

59th U.S. Rock Mechanics/Geomechanics Symposium
ABSTRACT: In rock engineering practice, Geological Strength Index (GSI) is a well-accepted method for rock mass classification with cross cutting applications. For instance, during blast design and support prediction in tunneling, stope and foundation planning and development.

Alternative Quantification of the Geological Strength Index Chart for Jointed Rocks
Geotechnical and Geological Engineering, 2017The paper suggests an alternative quantification of the Geological Strength Index (GSI) Chart published by Hoek et al. in Paper prepared for presentation at the 47th US Rock mechanics/geomechanics symposium held in San Francisco (2013). The engineering parameters proposed for the horizontal and vertical axes of the Chart are the most commonly used in ...

Application of Fuzzy Sets to Geological Strength Index (GSI) System Used in Rock Slope
Soils and Rock Instrumentation, Behavior, and Modeling, 2009The 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 ...

Modifications to the geological strength index (GSI) and their applicability to stability of slopes
International Journal of Rock Mechanics and Mining Sciences, 1999Abstract Determination of the strength of closely jointed rock masses is difficult since the size of representative specimens is too large for laboratory testing. This difficulty can be overcome by using the Hoek–Brown failure criterion. Since its introduction in 1980, the criterion has been refined and expanded over the years, particularly due to ...

The effect of variable rock mass properties on pile-rock interaction poses a great challenge to the design of stabilizing piles and numerical analysis of pile-rock interaction. The paper presents a novel method to estimate the properties of weathered bedrock, which can be applied to routine design of landslide-stabilizing piles for collivial landslides.

The Geological Strength Index Chart Assesment For Rock Mass Permeability
2017Determination of permeability of rock masses without testing is very chalenging due to the presence of complex discontinuitypatterns in rock masses. Many empirical approaches were proposed in the literature for estimation of rock mass properties.However, approaches based on rock mass classification systems in determination of rock mass permeability in ...
