Influence of overconsolidation ratio on hydromechanical behaviour of unsaturated silty soil under various shearing rates
Bibliographic record
Abstract
Due to the limited land resources in major cities, reclamation becomes an optimal option to solve this issue, unsaturated soil is often involved in these projects, and the hydro-mechanical behaviour of this type of soil significantly are affected by the stress history and time effect. In this study, the overconsolidation ratio (OCR) effect of unsaturated silt under different shearing rates was studied through a series of constant water content tests. The specimens were under an effective confining pressure of 400 kPa. The samples were unloaded to 100 kPa, and 50 kPa to achieve different values of OCRs (4 and 8). The samples with different OCRs were then dried from saturated state to initial suction = 100, 200, and 300 kPa via axis-translation, and then sheared at three different rates. The results show that higher strain rates led to a higher degree of saturation during shearing under different OCRs. The shear strength increased with increasing shearing rates while the maximum deviator stress decreased when OCR decreased. Higher OCRs resulted in larger volume change during shearing; similar behaviour was observed for increasing rates.

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.
