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.

Prediction of strength and deformability of an interlocked blocky rock mass using UDEC [PDF]

, 2017
The accurate prediction of strength and deformability characteristics of a rock mass is very challenging. In practice, properties of a rock mass are often estimated from available empirical relationships based on the uniaxial compressive strength (UCS ...

Crack Initiation, Propagation, and Failure Characteristics of Jointed Rock or Rock-Like Specimens: A Review

Advances in Civil Engineering, 2019
Rock masses are heterogeneous materials containing a large number of discontinuities, and the failure of the natural rock mass is induced by the crack propagation and coalescence of discontinuities, especially for the rock mass around tunnel or ...

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 ...

Strength of jointed rock masses [PDF]

Géotechnique, 1983
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 ...

Energy damage evolution mechanism of non-across jointed rock mass under uniaxial compression

Yantu gongcheng xuebao, 2019
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 ...
