Sample quality examination on silty soils
Bibliographic record
Abstract
Mediterranean deltaic environments typically produce soil deposits in which silts dominate, granular intercalations are frequent and the mineralogy includes an important carbonate fraction. One question still open is what sampling methods are most appropriate to recover undisturbed samples from these deposits and how best to evaluate disturbance on samples recovered from them. In this paper we present results from a testing campaign on silty deposits in which several sampling methods (Sherbrooke, Osterberg, Shelby) were used to recover sandy and silty clay samples from a Holocene lagoon deposit. Sample quality is established on oedometric specimens using normalized void ratio change on reconsolidation, comparisons of laboratory and field shear wave velocity and the ratio of suction to vertical « In situ » effective stress. Normalized void ratio change and shear wave based criteria are in agreement, and more so if the laboratory measurements are taken just after resaturation. The ratio of suction to normalised vertical effective stress shows no clear relation with normalized void ratio change.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
