<i>K</i><sub>0</sub>of sand measured by a plane-strain apparatus
Bibliographic record
Abstract
Experimental results are presented in this note to study the coefficient of lateral earth pressure at rest, K 0 , of sand measured using a plane-strain apparatus. The data are also compared with the K 0 measured by triaxial K 0 consolidation tests. The test data show that the K 0 values measured for specimens prepared using the water sedimentation method vary little with the void ratio of the soil, and therefore do not agree with the K 0 values calculated using Jaky’s equation, which uses the peak friction angles obtained from either plane-strain or triaxial tests. The K 0 values measured for specimens prepared using the moist tamping method follow a linear relationship with the void ratio. However, this relationship does not agree with Jaky’s equation either. The K 0 values obtained from tests on the specimens prepared using the two different preparation methods are different, which may reflect the influence of soil fabrics or structures on the one-dimensional compression behaviour of soil.

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.
