Coupled Thermo-Hydro-Mechanical (THM) processes are prevalent in a number of geotechnical engineering applications. Coupling temperature changes (T), groundwater flow (H) and mechanical deformation (M) affects the response of both geologic systems and overlaying structures. Generally speaking, the understanding of the mechanical behaviour of a soil allows predicting its responses under loading, to quantify its settlements and to analyse its stability. Due to the complex nature of soil as a composite material, soil mechanics involves a number of processes in which its three constituents (solid skeleton, water and air) are interacting with each other. For a number of engineering purpose, the coupled multi-physical behaviour of soils subjected to varying temperature and degree of saturation is of wide interest.
