GMS - GeoMechanical Survey

The software G.M.S. (GeoMechanical Survey) has the aim to represent and process the geo-structural survey of rock masses joints performed in-situ with the method of the compass and clinometer, according to the ISRM recommendations.

The joints in a rock mass condition, in a more or less evident way, the mechanical behavior of the rock and of the geotechnical model at the basis of any calculation. It is important, in order to correctly evaluate the stability condition, to have a precise description of the rock structure and joints, both in qualitative and quantitative terms.

For the determination of the rock's geotechnical model will be, therefore, illustrated the stages of joints survey, referring to geo-structural conditions (spacing, aperture, persistence) and to hydraulic and joint strength conditions (roughness, wall strength, degree of alteration, filling materials).

The application eGeoCompass developed by GeoStru generates a file compatible with GMS, useful for the joints survey.

The procedure used for performing the survey is described in the ISRM recommendations, "Suggested Methods for the Quantitative Description of Discontinuities in Rock Masses".
