The extension of geotechnical engineering applications and the research interest in multiphysics processes are becoming wider in recent years, mainly within the context of geoenvironmental, energy production, and geosciences areas. Topics such as crystal growth in geomechanics, fast sliding processes along faults and landslide surfaces, biological soil improvement, geothermal energy exploitation, waste confinement (at surface or at great depths using engineered barriers or host geological formations), soil pollution and remediation, CO2 storage, oil field subsidence phenomena and assessment of seals in hydrocarbon production, to cite but a few of them, are increasingly coming into prominence. These new fields of application require the incorporation of relevant and coupled thermo-hydro-chemo-bio-electro-mechanical phenomena, the evolution of which must be examined over important periods of time, and the introduction of new constitutive variables for a deeper understanding of the behaviour of geomaterials. Important efforts have been devoted in the last years to advance in the theoretical formulations, numerical analyses, constitutive modeling and laboratory techniques, as well as in the detailed examination of well documented field cases.
