Geotechnical Centrifuge

The geotechnical centrifuge, located on the Nantes Campus, has been one of the most active in the world since it was inaugurated in 1985 by research minister Prof. Hubert Curien. Featuring an earthquake simulator and an on-board remote-operated robot, the centrifuge can be used to study the behavior of geotechnical structures such as foundations, tunnels, offshore anchors, embankments and retaining structures in scale models. The results obtained enable us to observe and understand the phenomena involved: they can be directly transposed to full-scale structures via the application of similarity rules, and can be used to validate numerical simulations.
Controlled macrogravity tests are also used in the aeronautical, space and medical fields.
It is the only equipment of its kind for geotechnical applications in France, and one of the largest centrifuges in the world (5.5-meter radius, 2 tons on board, maximum acceleration 100×g). International exchanges with foreign centrifuge colleagues are thus regular, and international collaborations fruitful.
The geotechnical centrifuge is part of the GIS TheoREM network : "Réseau des Moyens d'Essais pour l'Hydrodynamique et les Énergies Marines Renouvelables" (theorem-infrastructure.org) as is the Cable fatigue test bench.
The team comprises 6 permanent researchers, 5 technicians and a part-time assistant. It welcomes several PhD students and post-docs each year.
