Abstract
Energy piles may be utilized for retaining structures, embankment reinforcements, and building foundations on a slope. In this study, a field test of a retaining energy pile subjected to horizontal loads has been carried out. The pile was subjected to thermal and thermo-mechanical loads before and after a pit excavation of 6 m deep, respectively. The non-uniform thermal and mechanical response at the cross-section due to heating and horizontal-load-induced bending has been recorded. A simplified mechanism of the normal strain and stress at the pile cross-section was introduced to infer the thermo-mechanical behavior of the energy pile. The results show that the restraint of the retaining pile markedly decreased at the depth of 1.5 and 4.0 m under the thermo-mechanical loads, compared to the case subjected to thermal load only. The bending behaviors (bending moment and horizontal displacement) indicate that there is a 10%–15% increase in bending moment when the energy pile was heated after the pit excavation. This effect needs to be considered at the most unfavorable section position. A possible positive effect is that heating up is beneficial for reducing the risk of tensile crack at the pile section due to the thermal compressive stress.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
