Microstructural model for delayed deformation of clay: loading history effects
Bibliographic record
Abstract
Microstructural observations of clayey soils indicate that clay particles are aggregated in units of low internal porosity (microporosity). Larger voids (macroporosity) between those units are associated with the flow of free water. Within this context, the secondary deformation of clay is interpreted as being a consequence of local mass transfer of water from the micropores to the macropores. The capability of a model based on this idea to reproduce the effects of loading history on the secondary compression of clay is explored. An experimental test program has been performed, secondary compression records have been interpreted within the proposed theoretical framework, and material parameters have been derived. The simulation of additional validation tests has been successful. The theory and model developed provide a unified framework for compression, as well as swelling secondary deformation.Key words: secondary consolidation, creep, preloading, overconsolidation ratio, oedometer tests, swelling.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
