Initial Observations on Laboratory Shear Loading Response of Sand-Silt Mixtures
Bibliographic record
Abstract
An experimental research program has been undertaken to investigate the monotonic shear loading response of sand-silt mixtures covering the complete range of sand-silt compositions in the mixtures. Initial observations and findings from the undrained monotonic triaxial compression and extension testing, as well as from drained triaxial compression tests, performed on non-plastic Fraser River silt, Fraser River sand, and 50%-50% mixture of the same two materials, are presented. The specimens of Fraser River sand were prepared using water-pluviation, and specimens of silt and sand-silt mixtures were prepared via slurry deposition. The results presented provide an initial insight to the complex behavioral patterns emerging from drained, undrained, compression, and extension loading responses, under some select sand and silt compositions. The findings illustrate the variation of the key soil parameters such as stiffness, shear strength/friction angle as the soil transitions from a coarse-grained to fine-grained matrix.

How this classification was reachedexpand
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.
