A basaltic rock mass is the relevant material for which strength properties must be defined and calculated model stresses must be compared to in order to more accurately predict brittle deformation.

Strength of jointed rock masses Géotechnique

2020-1-22  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

Relative scale and the strength and deformability of

1996-9-1  The basaltic rock mass is also weaker in tension, .2 to 2 MPa, than the intact basalt, -14 MPa. Similarly, the unconfined compressive strengths are reduced by com- parable amounts, from about 160 to 20-60 MPa for the welded tuff, and from 260 to 10-65 MPa for the basalt. Cohesive strengths of the rock masses are also reduced significantly.

Strength of massive to moderately jointed hard rock

2019-6-1  Hoek and Brown (2019) reiterated that the GSI rock mass characterization approach is set up to address two principal factors influencing the strength of a rock mass: (1) the blockiness; and (2) the surface conditions of the block-forming joints. It follows that the GSI-strength equations (Eq.,, ) are intended for blocky ground but not for massive to moderately jointed rock masses where

Limits on strength and deformation properties of

A study of strength and deformation measurements for basaltic rocks, along with consideration of the influence of fracturing using a rock mass classification system, documents the range of brittle response for basaltic rock masses. Although basalts vary widely in composition and other physical factors, many of the properties of a basaltic rock mass appear to vary within a factor of about 10.

Toughness and fracture mechanics (Chapter 10)

Rock strengths, such as tensile and shear strength, are one measure of its resistance to brittle failure. Another measure of rock resistance to brittle failure is the energy absorbed by the rock during fracture propagation. The critical energy absorbed is referred to as material toughness.
