Results of Long-Term Infiltration Tests on Unsaturated Swelling Clay
Bibliographic record
Abstract
Results of two long-term infiltration tests conducted in a triaxial cell are presented. Results of the testing are examined to assess mechanical and hydraulic behavior of an unsaturated swelling clay. In one test, radial flow is enforced with water pressure applied at the perimeter and drainage is allowed at the center of the specimen. In the second long-term test, vertical flow is applied with water pressure at the base and drainage is allowed out the top of the specimen. In both cases water flow into specimens and air flow at the downstream side is measured along with volume changes. Suction at the center of the specimen is measured in the vertical flow test using an embedded sensor. Water flow, volume change and suction responses are discussed to assess how flow and boundary conditions affect behavior. Differences in behavior during infiltration are noted due to anisotropy in the compacted specimens. Final distributions of water content, bulk density, dry density and degree of saturation are presented and discussed. Results show that these infiltration tests are important for understanding the physical movement of water through unsaturated swelling clay materials.

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.
