GeoScience Engineering, 2018 The anchor length db of rock bolts is often determined empirically by the insertion of the bond friction constant τb at the grout-rock interface. The relationship between force Fb by limit bond stress and bond length (or bond area) is their ratio. Within

Bedding control on landslides: A methodological approach for computer-aided mapping analysis [PDF]
, 2011 Litho-structural control on the spatial and temporal evolution of landslides is one of the major typical aspects on slopes constituted of structurally complex sequences. Mainly focused on instabilities of the earth flow type, a semi-quantitative analysis

The geotechnical evaluation of sandstone–claystone alternations based on geological strength index
Arabian Journal of Geosciences, 2014 The aim of this study is to classify heterogeneous deep-sea sediments (including sandstone and claystone) according to the geological strength index (GSI). Forty-nine locations have been selected from excavated Miocene deep-sea clastic sediments bearing slopes from the Kahramanmaras Basin (SE Turkey).

The Hoek–Brown failure criterion and GSI – 2018 edition
Journal of Rock Mechanics and Geotechnical Engineering, 2019 The Hoek–Brown criterion was introduced in 1980 to provide input for the design of underground excavations in rock. The criterion now incorporates both intact rock and discontinuities, such as joints, characterized by the geological strength index (GSI),

Lime stabilisation for earthworks: a UK perspective [PDF]
, 2014 Lime stabilisation is a versatile technique applied during earthworks operations. Modern soil recycling units are much more efficient at pulverising fill material and intermixing the added binder/water than machinery available 20 years ago.
