Abstract
Pipelines used in the distribution of potable water are a vital part of everyday life. The pipelines buried in soilbackfill are exposed to different deleterious reactions; as a result, the design factor of safety may be significantly degraded and, consequently, pipelines may fail prematurely. Proactive pipeline management, which entails optimal maintenance, repair, or replacement strategies, helps increase the longevity of pipelines. The effect of different deterioration mechanisms and operating conditions needs to be understood to develop good proactive management practices. In this paper, a Winkler-type analytical model is developed to quantify the contributions of different stress drivers, e.g., pipe material type and size, bedding conditions, and temperature. Sensitivity analyses indicate that the extent of the unsupported length developed as a result of scour has a significant influence on the flexural pipesoil response. As well, plastic pipes tolerate less loss of support than metallic pipes.Key words: jointed water mains, Winkler model, pipesoil interaction, elastoplastic soil.

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
