Cyclic thermomechanical response of fine-grained soil−concrete interface for energy piles applications

Understanding the behaviour of soil−structure interfaces is critical for addressing the analysis and design of energy geostructures. In this study, the interface failure mechanism of energy piles (where a shear band is detached from the surrounding soil that behaves under oedometric conditions) is experimentally analysed in the laboratory for saturated conditions. The choice of material (clayey soil and concrete), temperature range, and stress...
