Energy piles are highly favored for their excellent, low energy consumption in providing heating public residences. The temperature field changes the activity of diffuse double electric layer (DEL) on particle surface, thereby altering distribution stress soil and ultimately affecting mechanical properties interface between pile soil. Therefore, studying influence water content behavior soil–structure is crucial safety. This study used a modified temperature-controlled direct shear apparatus to obtain interface. Then, test results were analyzed discussed. Finally, three obtained: (1) bentonite (wbent) had significant impact stress–shear displacement curve interface; when wbent was less than wp bentonite, τ-l exhibited softening response, then displayed hardening response. (2) strength gradually decreased with increase wbent. (3) increased increasing under various vertical loads.
