Coupled THMC Analysis in Energy and Environmental Geomechanics
The involvement of geotechnical and 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 systems behaviour under coupled THMC conditions represents huge challenges for our profession, but also extraordinary opportunities to gain a better understanding of soils and rocks behaviour under such complex extremes.
In this lecture, recent improvements in our understanding of geomaterials behaviour subjected to simultaneous THMC perturbations will be presented, as well as the incorporation of the main features associated with the THMC behaviour of soils and rocks in constitutive and numerical models.
Some of the applications to be briefly discussed in this seminar include: behaviour of swelling clays and pelletized mixtures typically used in the design of engineered barriers and seals; performance of geo-thermal structures; behaviour of hydrate bearing sediments; fault reactivation triggered by gas injections; and design of underground compressed air storage system.
