Influence of degree of interlock on confined strength of jointed hard rock masses
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.

Electrical resistivity of a jointed rock mass with an anomaly
It is of great importance to estimate the spatial characteristics of a jointed rock mass in a diverse range of disciplines. Although electrical resistivity prospecting can facilitate this, limited attempts have been made to perform electric field ...

Strength of jointed rock masses [PDF]
Jointed rock masses comprise interlocking angular par- ticles or blocks of hard brittle material separated by discontinuity surfaces which may or may not be coated with weaker materials. The strength of such rock masses depends on the strength of the intact pieces and on their freedom of movement which, in turn, depends on the number, orientation ...

Strength of massive to moderately jointed hard rock masses
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 ...

Energy damage evolution mechanism of non-across jointed rock mass under uniaxial compression
Energy accumulation and energy release appear evidently during the whole deformation process of jointed rock mass. In order to explore the energy evolution law of jointed rock mass under loading condition, the uniaxial compression experiment and the ...

Analysis on the evolution law of creep-fatigue failure energy of deep anchored jointed rock mass
In order to explore the mechanical properties of deep rock masses under disturbance loads such as blasting and excavation, laboratory tests of anchored rock masses under creep-fatigue loads were carried out, and the law of energy evolution was further ...
