Abstract Due to the relatively different mechanical and physical properties of soils structures, interface plays a critical role in transfer stress strain between them. The stability safety geotechnical structures are thus greatly influenced by behavior at soil–structure interface. It is therefore important focus on unique characteristics that set apart from other geomaterials while examining behaviour. Understanding mechanism modelling principles these interfaces becomes crucial step for secure design investigation soil-structure interaction (SSI) issues. Moreover, deal with this soil-environment problem, classical soil mechanics formulation must be progressively generalised order incorporate effects new phenomena variables SSI Considering variety energy geostructures emerging nowadays, it comprehend thermo-hydro-mechanical (THM) behaviour objective study fill information gap as concisely possible. A review provided along state-of-the-art interface, including testing tools measurement methods, basic deformation mechanisms, constitutive models, well their applications numerical simulations. This explains how loading influences mechanisms critically examines boundary conditions, properties, environmental factors, structure type THM zones structural elements. validity reliability shear stress-displacement models also covered paper. Lastly, trends recent advancements recommended research.
