Abstract
Abstract As the forest industry moves into second growth stands with smaller tree diameters the design of gravel-decked log stringer bridges becomes more critical. This article considers the stress field at the base of the gravel decking. The results of this article indicate that stress equations derived from elastic theory for a semi-infinite solid underestimate the magnitude of the maximum vertical stress at the base of the gravel decking. Therefore, a finite element model (FEM) was used to estimate the stress field at the base of the gravel decking. A single equation was fit to the FEM results for a range of gravel depths using a unit load. This equation provides a method for estimating the vertical stress at the base of the gravel decking that is a function of the horizontal distance from the center of the tire contact patch and the total depth of the gravel decking.

Full frame distilled prediction
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
