Glossary

Sampling of ground water for laboratory analysis using equipment like bailer and/or variable displacement submersible pumps.

Technique for sampling of soil, concrete or masonry structures in reinforced concrete cylindrical (carrots) and based on the use of core drilling or drilling probes.

Set of investigations, inspections and analysis of geological character and physical-chemical aimed at defining the status of environmental contamination of soils and surface waters and groundwaters in a given site.

Set of surveys, tests and analysis of geological and geotechnical character aimed at the definition of the nature and geotechnical properties (Geotechnical model) subsurface volume examined.

Installation in boreholes of inclinometer and piezometric pipes, tracking equipment of hydro-geological and geotechnical parameters.

Mineral exploration activities conducted with geomechanical methods (drilling and surveys) and geophysical methods.

Collection of evidence and mineral exploration activities conducted using instrumental measurements to define the physical properties of the soil volume investigated such as the speed of propagation of elastic waves, density, electrical conductivity, magnetic characteristics of reflectivity, etc.

Geotechnical tests and collection of assets for the investigation of the subsoil conducted both in the field (on site) in the laboratory for the determination of geological and geotechnical characteristics (permeability, mechanical strength, etc.) of land on a particular site.

Surveying technique for the relief of altimetric points, most often applied to the structural monitoring of buildings, monuments and structures in General.

Detection of water levels of groundwater geognostic purposes, or for hydrogeological monitoring of groundwater aquifers.

In part, structural and environmental geotechnical the "monitoring" is understood to be monitoring the evolution of phenomena such as soil deformations, hydro-geological parameters, fissures, cracks, lesions, and inclinations of structures and buildings, subsoil contamination etc., with reliefs and prolonged measures over time.

Detection technique in electronic, automatic time and distance learning using on-line technologies for structural monitoring, environmental and geotechnical parameters of interest.

Long-term relief the magnitude of vibration generated in three directions x, y and z on the ground or on a given structure from a variety of sources and measured using electronic detection tools.

Test method for structural diagnosis based on experimental measurements in situ deformability characteristics of a significant portion of the wall through the use of special flat load cells (flat jacks) stuck into the wall.

The examinations, tests and structural surveys conducted using nondestructive methods is, that invasive (direct and probing essays), for the identification of properties of r.c. structures or walls of a building or monument complex.

Tests and surveys conducted to test or verify – through experimental measurements of bearing capacity of soils and concrete structures such as slabs, pilings, etc.

The examinations, tests and surveys conducted using methods that do not alter the material and do not require the destruction or the removal of samples from the structure under consideration aimed at research and identification of structural defects of the structure itself. Among the main types of tests: concrete hammer, combined ultrasonic, SONREB, pull-out, pacometriche.

Geotechnical survey methodology of subsoil based on in-situ experimental measurement of the characteristics of mechanical resistance offered by a static or dynamic penetration of a conical tip placed underground.

Execution of measures of angles, distances and elevation performed using equipment like total stations and GPS i/o for reconstruction and impersonation graphics, detailed, more or less of a particular area of emphasis.

Execution of measurements of geometric and structural characteristics of artifacts and building structures made using instruments such as total stations, disto and/or nondestructive detection tools for reconstruction and impersonation graphics, more or less detail, architectural development and structural caratterishche.

Methodology of geophysical survey to be carried out on the surface (seismic stendimenti) or in boreholes suitably packaged (down-hole seismic tests, cross-hole) based on the speed of propagation of elastic waves refracted in the subsoil.

Underground drilling activities conducted by mechanical means (augers and probes) for sampling of subsoil and geotechnical tests on site (S.P.T. tests, permeability tests Lefranc-Lugeon then, etc.).

Line along which speed measurements of the propagation of seismic waves in the subsoil or electrical resistivity to derive information about the features, hydrological, geotechnical stratigraphic of the medium traversed.
