The involvement of geotechnical/geomechanical engineers in problems comprising unprecedented Thermo-Hydro-Mechanical and Chemical (THMC) conditions is every time more frequent, particularly in applications related to geo-environmental and geo-energy problems. The prediction of geo-engineering system behavior under coupled THMC conditions represents huge challenges for our profession, but also extraordinary opportunities to achieve a better understanding of soils and rocks behavior under such complex extremes. The realization of this requires both, advanced experimental and numerical investigations. In this lecture, recent improvements in our understanding of geomaterials behavior subjected to simultaneous THMC perturbations will be discussed, as well as, the incorporation of the main features associated with THMC behavior of soils 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 and seals, behavior of hydrate bearing sediments, fault reactivation triggered 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 during gas injection.
