Evaluation of the swelling pressure for expansive soils
Bibliographic record
Abstract
The interaction between light structures and expansive soils as mainly active clays was studied since the 1950's. The first stage in foundation design on this problematic soil is the evaluation of the swelling potential, based on which one identifies the clay's activity and its correlation with the value of the swelling pressure (p s ) for the decisional support of the geotechnical design (p effective > p s ). In the literature there are many formulas that can be used to predict the swelling pressure based on the correlation between various geotechnical parameters. This paper provides the swelling pressure as correlation with the consistency index (CI) and the liquid limit (LL), by linear regression of the experimental results for the 56 active clays from seven countries. Using the analytical methods, one can predict the total heave of a floor slab founded on expansive clay. The validity of the proposed correlation has been tested in the prediction of the total heave in the centre of a floor slab for a light industrial building in North-Central Regina, Saskatchewan, Canada.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
