Atterberg Limits and Remolded Shear Strength—Water Content Relationships
Bibliographic record
Abstract
Abstract The remolded undrained shear strength (sur) is of importance in many geotechnical applications. This paper uses published regression analyses for strength variation with water content (w) to draw some generalized conclusions on soil strength behavior, including values of sur mobilized for the Casagrande liquid limit (LL) and plastic limit (PL) conditions and, hence, the shear strength variation occurring over the plastic range. Reported methods of deducing strengths from measured values of water content (w) at the Atterberg limits are reviewed, many of which assume a strength variation of 100 over the plastic range. Regression analysis of reported log w: log sur correlations for 14 mineral soils and four organic sediments indicated that the strength variation is generally not 100 and can vary significantly between soils. Hence, a new approach is proposed for predicting values of remolded undrained strength mobilized for different water contents. Whereas existing formulations are based on empirical sur values associated with the Atterberg limits, the proposed approach is based on direct strength measurements along with water contents for two test specimens.

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.
