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.

Study on Interfacial Crack Initiation of Jointed Rock Mass Based on Interface Fracture Mechanics
Fractal and Fractional, 2022 The fracture of interfacial crack is the main failure type of jointed rock mass. Therefore, it is very important to study the interfacial fracture of jointed rock mass. For the similarity of jointed rock mass and composites (all are composed by two parts,

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 ...

Study on the breaking process of jointed rock mass by disc cutters based on digital image correlation and infrared thermography [PDF]
E3S Web of Conferences, 2021 Jointed rock masses are frequently encountered during the TBM excavation. To investigate the rock breakage mechanism of jointed rock mass by disc cutter and precursory information before rock failure, a series of indentation tests were performed on shear

Research on elasto-plastic viscous fatigue constitutive model of jointed rock
Rock and Soil Mechanics, 2021 The jointed rock mass exhibits an obviously instantaneous plastic strain under fatigue loading, and thus it is imperative to establish a fatigue constitutive model of jointed rock considering instantaneous plasticity.
