Geotechnical monitoring: projects
The applications of Earth System instrumentation in geotechnical and structural measurements.
Overview of projects
Browse the sections to discover some of the projects that use Earth System instrumentation.
Motorway and railway tunnels
In tunnels, geotechnical monitoring is essential to ensure the stability of excavation fronts, vaults and linings. Instrumentation is also used to detect ground displacement, structural deformation, interstitial pressure and possible convergence.
Underground stations
In railway and metro stations, geotechnical monitoring is used to assess the stability of foundations, load-bearing structures and adjacent soils by recording ground movements, structural deformation and changes in interstitial pressure.
Metro System
In underground railway systems, geotechnical measurements are used to assess the stability of tunnels and supporting structures, monitor ground movements, structural deformation and changes in interstitial pressure caused by excavations and therefore also by the passage of trains.
Buildings
In buildings, geotechnical instrumentation allows the interaction between the structure and the underlying terrain to be measured in order to monitor any differential subsidence of foundations, ground movement caused by excavations or loads, and changes in interstitial pressure.
Motorway and railway viaducts and bridges
For viaducts and bridges used for roads and railways, geotechnical instrumentation allows the stability of foundations, pillars and superstructures to be evaluated by monitoring movements of the ground, any structural deformation and changes in interstitial pressure.
Dams and hydroelectric plants
In the hydroelectricity sector, geotechnical monitoring is essential to determine the stability of the foundations, slopes and structures of a dam. The instrumentation is used to monitor ground movement, changes in interstitial pressure and structural deformation, to ensure the safety of the plant.
Other applications
Geotechnical measurements are also used in numerous other fields, including port and maritime works, gas pipelines, mines, quarries, airports, land consolidation and reclamation, to assess the stability of structures and changes in environmental conditions.
