Strength of massive to moderately jointed hard rock masses

open access: yesJournal 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

open access: yesJournal 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.

Application of Soft Computing Techniques to Estimate Cutter Life Index Using Mechanical Properties of Rocks

open access: yesApplied Sciences, 2022
The wear of cutting tools is critical for any engineering applications dealing with mechanical rock excavations, as it directly affects the cost and time of project completion as well as the utilization rate of excavators in various rock masses.

Different Stress Paths Lead to Different Failure Envelopes: Impact on Rock Characterisation and Design

open access: yesApplied 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 ...

Stochastic Model Generation of Porous Rocks and Study on 2D Pore Morphology Influencing Rock Strength and Stiffness

open access: yesFrontiers in Materials, 2022
With the increasing usage of porous rocks in engineering construction, their well-performed properties (e.g., permeability and heat insulation) have attracted increasing attention from researchers in engineering geology. In nature, the vesicles in porous

Strength Criterion of Rocks

open access: yesSoils and Foundations, 1980
ABSTRACT To investigate the strength characteristics of soft rocks, consolidated-drained triaxial compression tests were performed with mudstones, siltstones, tuff, weathered granite and so on. Maximum stress of applied confining pressure was about 30 MPa.
