Strength of massive to moderately jointed hard rock masses
Journal of Rock Mechanics and Geotechnical Engineering, 2019 The Hoek-Brown (HB) failure criterion and the geological strength index (GSI) were developed for the estimation of rock mass strength in jointed and blocky ground where rock mass failure is dominated by sliding along open joints and rotation of rock ...

Influence of degree of interlock on confined strength of jointed hard rock masses
Journal of Rock Mechanics and Geotechnical Engineering, 2020 The strength of jointed rock mass is strongly controlled by the degree of interlock between its constituent rock blocks. The degree of interlock constrains the kinematic freedom of individual rock blocks to rotate and slide along the block forming joints.

Applied Sciences, 2023 The strength of rock is a non-intrinsic property, and this means that numerous parameters influence the strength values. In most laboratory experiments, specimens are free of stress at the start of the tests, and the load is increased systematically ...

Effect of Intermediate Principal Stress on the Strength, Deformation, and Permeability of Sandstone
Energies, 2018 Although the mechanical behaviors and flow aspects of sandstone have been previously investigated, studies of the effect of the intermediate principal stress (σ2) on the strength, deformation, and permeability of sandstone are lacking. In this work,
