Abstract

fetched live from OpenAlex

A detailed laboratory testing programme was conducted on undisturbed sensitive Leda clay samples obtained from Quebec area (Breckenridge and Outardes-2) and on relatively uniform sands (Fraser River sand and Ottawa sand) under triaxial loading mode.Monotonic and cyclic behavior of sensitive Leda clay were studied by performing large strain tests at various consolidation conditions.Small strain stress controlled quasicyclic tests were conducted on both clay and sand to establish site-specific modulus reduction and damping ratio curves at small strain amplitudesThe shear strength and cyclic resistance of Leda clay under triaxial testing mode is noted to be significantly higher than the previously reported values under simple shear loading conditions.Further, it is confirmed that both consolidation stress and over consolidation ratio influence the monotonic shear strength of clay.Site specific modulus reduction and damping ratio curves are proposed for Leda clay, Fraser River sand and Ottawa sand.The proposed dynamic curves for Leda clay indicate that the behavior of sensitive clays does not follow any particular curve proposed in the literature for non-sensitive clays.These results also suggest that modulus reduction and damping curves are loading path dependent.

Not 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.
