Brittle strength of basaltic rock masses with applications to Venus Jun 25, 1993 Rock mass strength is defined by three parameters including unconfined compressive strength of

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.

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

Deformability and strength of discontinuous rock masses. In Myer, Cook, Goodman & Tsang (eds.), Fractured and Jointed Rock Masses: A constitutive model and FEM analysis of jointed rock masses.

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.

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

2018-9-21 Strength of jointed rock masses 2 Strength of jointed rock masses Evert Hoek, Golder Associates, Vancouver, Canada Synopsis Jointed rock masses comprise interlocking angular particles or blocks of hard brittle material separated by discontinuity surfaces which may or may not be coated with weaker materials.

Brittle strength of basaltic rock masses with applications. Rock mass strength is defined by three parameters including unconfined compressive strength of intact basalt and two others related to the degree of fracturing of the material Experimental results for elevated temperature extend the applicability of these parameters to the near

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.

Cohesive strengths of the rock masses are also reduced significantly.

From the geological structure of the columnar jointed rock mass, a visual model was established in software AUTOCAD by programming based on the algorithm of the Voronoi diagram. Furthermore, a program to convert the AUTOCAD model into 3DEC (3-dimensional distinct element code) model was developed, and a numerical model was established in 3DEC. Moreover, the results of triaxial

Rock mass strength is defined by three parameters including unconfined compressive strength of intact basalt and two others related to the degree of fracturing of the material. Experimental results for elevated temperature extend the applicability of these parameters to the near

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. For example, the various strengths of a rock mass are less than that of intact material of the same composition.

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.
