GERSDisplay the main menu


The agents of the department GERS conducting targeted research and offer their expertise in four thematic fields:

  • Geotechnical Engineering
  • Natural hazards
  • The management of urban water
  • Auscultation of the non-destructive methods of materials and close the basement.

In each of these fields, the objective is to develop new knowledge, methods or tools for advancing the engineering and management practices.


Research conducted are often applied in nature and combine characterization laboratory material properties testing models, experimental in situ monitoring, the development of numerical models and sometimes hardware. As necessary, more basic research on materials and processes (solid state NMR on soil treated with lime for example) or on the methodologies (regional Bayesian statistics, interferometry coda waves, guided waves) are performed .

GERS officers also actively engaged in scientific and technical associations, scientific advice and the standardization and produce expertise, essential activities to ensure the exchange with professional circles and the emergence of scientific issues related to the applications and meet operational requirements.



Distribution of activities of the department GERS

Some research topics of the recent period

  • Study of shrinkage and swelling mechanisms of soils and impacts on the frame to meet the strong increase in damage compensated for drought
  • Effect of cyclic loading on the behavior of foundations to improve design methods for wind foundations, including,
  • Evaluating new stormwater management modes accompaniment city in the alternative technical development policies, eco-neighborhoods and the rain tax
  • Study of the conditions of soil liquefaction and the holding of foundations under seismic valuing the recent earthquakes records, including the Tohoku earthquake / Fukushima,
  • Determination of conditions for effective treatments of soils for better recovery of materials in place during earthmoving operations,
  • Evaluation of the sensitivity to erosion of the dikes and scour and development of new modes of auscultation to accompany national dikes restoration policy: map "dykes"
  • Proposed new flash floods forecasting tools contributing to the plan "quick submersions"
  • Development of geophysical techniques for the detection and monitoring of damage applied to experimental sites for underground storage of nuclear waste.
