Assessment of the Relationship between Undrained Shear Strength and Geotechnical Parameters for Sensitive Clays of Eastern Canada
Bibliographic record
Abstract
Eastern Canadian clays are characterized by high sensitivity and compressibility and warrant the need for an appropriate estimation of the undrained shear strength for a safe geotechnical design. A multivariate geotechnical database consisting of natural water content, Atterberg limits, undrained shear strength, effective vertical stress, preconsolidation pressure, and overconsolidation ratio from 49 sites in Eastern Canada is compiled from literature for this purpose. The primary objective of this study is to analyse the dependence of undrained shear strength on the aforementioned parameters and propose a correlation that satisfies practical conditions through regression analysis. Bias and uncertainties of existing empirical correlations are assessed. A comparative study is also made with sensitive clays of Norway and Sweden. The results show the poor correlation of Eastern Canadian clays with index parameters and their strong dependence on the stress history of the soil.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
