PHYSICAL PROPERTIES OF ROCK

general, rock and rock mass properties can be divided into five groups: C physical properties (durability, hardness, porosity, etc.), C mechanical properties (deformability, strength), C hydraulic properties (permeability, storativity), C thermal properties (thermal expansion, conductivity), and C in situ stresses.

Evaluation of rock mass strength criteria

of the most common ways of estimating the rock mass strength is by using a failure criterion. The existing rock mass failure criteria are stress dependent and often include one or several parameters that describe the rock mass properties. These parameters are often based on classification or characterisation systems. A comprehensive literature

STRENGTH PROPERTIES OF ROCKS AND ROCK MASSES 1 ...

Rock mass strength is scale dependent and varies with the volume of rock under consideration. The modes of failure of intact rock are multiple. Rock can fail in tension, compression or shear. This depends on the load configuration, the geometry of the problem and how the loads are applied and distributed. A rock mass can also fail in tension ...

Classifications of Rock Properties - RockMass

Intact rock strength . The uniaxial compressive strength of a rock material constitutes the highest strength limit of the rock mass of which it forms a part. It is determined in accordance with the standard laboratory procedures. For the purpose of rock mass classification, the use of the well -known point load strength index can be useful as the

Laboratory Testing and Interpretation of Rock Properties

Deformation and strength properties of intact specimens aid in evaluating the larger-scale rock mass that is significantly controlled by joints, fissures, and discontinuity features (spacing, roughness, orientation, infilling), water pressures, and ambient geostatic stress state.
