DESCRIPTION:Dr. Alessio Ferrari\, EPFL-ENAC-LMS\nThe geomechanical behavio
 ur of shales is quickly becoming one of the most important issues in moder
 n geomechanics\, largely driven by petroleum industries (i.e.\, the extrac
 tion of shale gas)\, the sequestration of CO2 and the nuclear waste geolog
 ical storage. In any such application\, a deep understanding of the hydro-
 mechanical behaviour of the involved materials is of primary signicance. A
 dvanced experimental techniques and apparatuses have been developed at the
  Laboratory for Soil Mechanics of the EPFL for testing the thermo-hydro-me
 chanical behaviour of shales. Some of these advances in shale testing are 
 presented. A methodology established for the analysis of the water retenti
 on behaviour in non-isochoric conditions is introduced\; the method allows
  for the determination of the main drying and wetting paths in addition to
  the volume change response upon total suction variations. A high-pressure
  oedometric cell is then presented\; the apparatus allows for the analysis
  of the transition from the pre-yield behaviour to the normally consolidat
 ed state. The analysis of the settlement versus time curves yields informa
 tion on the permeability of the material as a function of the void ratio. 
 The test results are illustrated for two Mesozoic shales from the northern
  region of Switzerland\, namely\, the Opalinus Clay from Mont Terri and th
 e so called “Brown Dogger” from the Schlattingen site in the Molasse B
 asin.
