“…Pincus et al [6] found that the direct shear test was able to consider the effect of volume deformation of the soil around the pile on the shear characteristics, which is consistent with the volume deformation during the shear process of the pile-soil contact surface in reality. Since energy piles have both bearing and heat transfer functions, the shear characteristics of the pile-soil contact surface under temperature action need to be investigated [7]. There are many research results of pile-soil contact surface shear tests under varying temperatures that mainly focus on the relationship between the shear stress and shear displacement of the pile-soil contact surface.…”

In this paper, a finite element numerical model of thermal-hydro-mechanical of energy piles under multi-layer geological conditions was established, and field tests of ultra-long energy pile (1000-mm-diameter, 44-m-long) were carried out to reveal the temperature distribution and mechanical properties of energy pile under typical working conditions. Based on the analytical results, a softening shear model of the energy–soil interface under the condition of large shear displacement was proposed with the load transfer method, and the reliability of the model was verified. The model can simulate the shear–displacement relationship of the pile–soil interface under different geological conditions.
