DESCRIPTION:Professeur Marcelo SANCHEZ\, Zachry Department of Civil Engine
 ering TAMU\, Texas A&M University\, USA\nThe involvement of geotechnical/g
 eomechanical engineers in problems comprising unprecedented Thermo-Hydro-M
 echanical and Chemical (THMC) conditions is every time more frequent\, par
 ticularly in applications related to geo-environmental and geo-energy prob
 lems. The prediction of geo-engineering system behavior under coupled THMC
  conditions represents huge challenges for our profession\, but also extra
 ordinary opportunities to achieve a better understanding of soils and rock
 s behavior under such complex extremes. The realization of this requires b
 oth\, advanced experimental and numerical investigations. In this lecture\
 , recent improvements in our understanding of geomaterials behavior subjec
 ted to simultaneous THMC perturbations will be discussed\, as well as\, th
 e incorporation of the main features associated with THMC behavior of soil
 s and rocks in constitutive and numerical models. Some of the topics to be
  briefly discussed in this seminar include: behavior of swelling clays and
  pelletized mixtures typically used in the design of engineered barriers a
 nd seals\, behavior of hydrate bearing sediments\, fault reactivation trig
 gered by gas injection\, behavior of frozen soils\, geo-thermal structures
 \, CAES design\, formation and propagation of desiccation cracks in soils.
  Particular attention will be paid to the problem of fault reactivation du
 ring gas injection.
