Descriptions
This work points out the main criteria for geotechnical characterization in rock masses, is described the steps of each fases of characterization and is enfasized the importance of choosing the correct group of parameters to established a suitable geotechnical classification system and help resolving actual engineering problems. An aplication of this methodology is made to a future marble underground exploitation in Estremoz-Borba-Vila Viçosa.
With the samples collected in the drillings and according to their orientation in the holes the geomechanical classification of the rock material was carried out. This classification was mainly related to the determination of the parameters of deformability and strength of the materials in the laboratory. For the geomechanical characterization of the rock material, almost 1700 tests were carried out according to the ISRM standards. The parameters of strength and elasticity were determined for the material of each of the specimens, using uniaxial compressive tests. Material strength parameters, uniaxial compressive strength, tensile strength, cohesion and friction angle were determined by performing uniaxial and triaxial compressive tests, flexure, direct shear tests. These tests were carried out at the Geomechanics Laboratory of GEOLAB-CERENA, in accordance with the ISRM standards.
