PHYSICAL PROPERTIES OF ROCK
ceae.colorado.edugeneral, 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
www.diva-portal.orgof 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
