The effect of rock classes on the relation between uniaxial compressive strength and point load index

Bulletin of Engineering Geology and the Environment, 2009
Uniaxial compressive strength and point load tests were carried out on 17 igneous, 16 metamorphic and 19 sedimentary rocks and the values correlated with their Is values. The influence of the different rock type was investigated using regression analysis and the derived equations were statistically tested.

Recommendation of Specimen Geometry in Determining Point Load Strength Index for Anisotropic Rocks

International Geomechanics Conference
ABSTRACT: The point load strength index (Is(50)) is the critical parameter in evaluating the mechanical response of rock. Due to its ease in specimen preparation, this index test becomes even more important for calculating the strength index of layered anisotropic rocks.

Relations Between Geologic Strength Index, Discontinuities and Point Load Strength Index of Some Rocks in Kemi Mine

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.

Granites of Dublin, Ireland: uniaxial compression strength, point load index and correlation analysis

Quarterly Journal of Engineering Geology and Hydrogeology
While the uniaxial compression strength ( UCS ) test is the gold standard for determining the UCS of rock for geotechnical and mining applications, empirical correlations between UCS and other test measurements such as point load index ( PLI )

A validation study for the estimation of point load index at varying slenderness ratio

2019
This work reports the results of an experimental validation study of a recently developed analytical solution, by the group authors, for the measurement of rock tensile strength using diametrical point load strength index. Results, obtained from a series of more than 200 point load and Brazilian tests with a wide range of rocks, suggest that the ...
