Preliminary Evaluation of the Effects of the Unsaturated Conditions on the Pre-Shearing State of Stress of Quarzitic Tailings
Bibliographic record
Abstract
This paper deals with the laboratory investigation of the compressibility of a silty soil, representative of tailing wastes, under unsaturated conditions.The experimental activity consisted of a series of conventional oedometer tests to analyse the stress-strain response at variable suction levels, and a series of water retention tests to determine the water retention curves to be later used for the theoretical interpretation, which was conducted according to the Barcelona Basic Model (BBM).The dependency of the soil compressibility, 1d-Normal Compression Line (1d-NCL), pre-consolidation stress and recompression index on the matric suction is preliminarily analysed.Both the compression and recompression indexes of Stava tailings were observed to decrease with suction.The experimental evidence also showed an increase of the pre-consolidation stress with suction, and the results find a good agreement with literature data obtained on more standard soils..

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.
