Abstract
By 2023, global utility-scale solar photovoltaic (PV) installations are expected to reach almost 1,000 GW. Ground-mounted solar PV racking systems typically consist of a steel structure supported by drilled or driven pile foundations. Due to the relatively light-weight nature of solar racking installations, environmental conditions such as hazards due to frost action are of critical importance for PV ground-mounted systems. Pile uplift due to adfreeze stresses from frost action typically controls the foundation design for projects in the northern portions of the United States and in Canada. This paper presents a discussion of important considerations for geotechnical design for utility scale solar PV racking systems, with a focus on frost action risk, typical evaluation methods, design recommendations, and mitigation options for impacted sites. The important role of a typical design process including performing appropriate geotechnical investigations and incorporating results of pile load testing for optimization of design are also discussed.

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
