DELAGE Pierre

Professor at Ecole des ponts ParisTech

Corresponding member, French Academy of Agriculture

delageATcermes.enpc.fr

  • Civil Eng. from Ecole Nationale des Ponts et Chaussées (1976)
  • Ph. D. in Engineering Geology, Ecole des mines de Paris - U. Paris VI (1979)
  • Post-doc fellow, Univ. Sherbrooke (Canada) (1980 - 1981)
  • Visiting Prof., Nanyang Tech. Univ. Singapore (2010-2011)
  • “Habilitation à diriger les recherches” ENPC-ENS Cachan-UMLV (1996)

Pierre Delage has been significantly involved, in the 80’s, in the development of CERMES (the geotechnical group of Ecole des Ponts, now included in Laboratoire Navier), that he directed from 2003 to 2010. He developed researches on the fundamentals mechanisms governing the macroscopic response of multi-phase soils and rocks submitted to changes in stress, water content and temperature (Thermo-Hydro-Mechanical couplings), with some pioneering contributions on the role of the changes in the pore size distribution in the volume change behaviour of soils, the stress-strain and failure behaviour of unsaturated soils or the thermal response of claystones. His researches concerned various applications related to sensitive clays, deep marine sediments, unsaturated soils, compacted soils, loess, oil reservoir chalks, oil sands, claystones and shales and, more recently, Martian regoliths, in the framework of the NASA InSight mission on Mars. He is a corresponding member of the French Academy of Agriculture, has been Chief editor of the “Revue Française de Géotechnique” and “Géotechnique Letters” (ICE London). He has been or still is member of various editorial panels (Géotechnique, Computers and Geotechnics, Geotechnical Testing Journal, Geomechanics and Geoengineering, Rivista Geotecnica Italiana). He organised, with E. Alonso, the 1st Int. Conf. on Unsaturated Soils in Paris (1995), played an active role in the 18th Int. Conf. on Soil Mechanics and Geotechnical Engineering (Paris 2013) and chaired the 3rd European Conf. on Unsaturated Soils (Paris 2016). He serves since 2013 as Chair of the Technical Oversight Committee of the International Society of Soil Mechanics and Geotechnical Engineering, in charge of supervising the activities of the 32 Technical Committees of the ISSMGE, under both Roger Frank and Charles Ng’s Presidential terms.
