Abstract Summary
This study presents an experiment based on a small-scale pile model installed in saturated kaolin clay to study the long-term behavior of energy piles under thermal cycles and inclined mechanical loads. Three levels of horizontal loading of 35, 71, and 109 N were applied to the pile head while keeping the constant vertical mechanical loading of 100N. Fifteen thermal cycles with an amplitude of ±4.5℃ were applied to the pile under each inclined mechanical level. The results show an increase in irreversible pile head settlement and horizontal displacement with thermal cycles but with a gradually decreased accumulation rate.
