Settlement of deep footings in reconstituted sand
Bibliographic record
Abstract
The paper examines methods for predicting the settlement of deep footings in reconstituted sand. Results from vertical load tests on deep circular plates within a laboratory pressure chamber are interpreted using data from triaxial tests, cone penetration tests (CPTs), and pressuremeter tests obtained for the same reconstituted sand. A simple nonlinear CPT-based relationship is shown to match the response observed in the plate tests and be consistent with finite element analyses as well as other comparable physical tests. The relationships between foundation stiffness and the sand’s small-strain stiffness, its stiffness at 50% mobilized strength, and its response to pressuremeter loading are also explored. Comparisons with full-scale tests in the field reveal a strong effect of ageing on foundation stiffness, which appears to be better captured by small-strain stiffness than CPT end resistance. Measurements confirm that vertical loading of a deep plate is analogous to the expansion of a spherical cavity.

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.
