Compacted Unsaturated Soil Behavior in a Large Scale Laboratory Test
Bibliographic record
Abstract
This paper discusses the responsive behavior of an unsaturated clay soil to compaction conditions in a large-scale laboratory test. A laboratory test was developed in order to use a field geo-gauge to measure and observe soil stiffness behaviors. The soil was compacted at water contents ranging from dry to wet of a standard proctor optimum moisture content. Monotonic loading conditions were employed and stiffness measurements were determined with each incremental compaction effort. The responsive behaviors of the mechanical and dynamic properties with changes in void ratio of the compacted soils are discussed. Generally, the resiliency of the soil is shown by increases in stiffness with changes in void ratio due to incremental compaction efforts. An existing method of estimation of matric suction was employed in the analyses of the data. The trends of stiffness and matric suction of the clay based on the large-scale laboratory tests were found to be typical of trends from other generally used laboratory test methods.

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.
