Permeability Behavior of Expansive Rock of Middle Routeof South to North Water Transfer Project
Bibliographic record
Abstract
The double ring field tests,Guelph tests and laboratory reconstituted permeability tests were carried out respectively to investigate the permeability behaviors of the untreated and treated expansive rock slopes in the main canal of the Middle Route of the South to North Water Transfer Project.The results of the double ring field tests show that both the permeability coefficient and infiltration depth of the marlite are greater than those of the clay stone,respectively,and that the stable permeability coefficient and infiltration depth obtained in geogrid reinforced field are one-fourth and one-second of those receirved in the treatment field with soil bags,respectively.Geogrid reinforced treatment has been proved to be an effective measure for the expansive rock slope.The results of laboratory reconstituted permeability tests show that the permeability coefficient of remolded marlite samples is greater than that of the reconstituted clay rock when their dry densities are the same with natural water content.The decrease of the permeability coefficient of the marlite is more significant than that of the clay rock with the same increase of the dry density.Moreover,the measured permeability coefficients of marlite and clay rock from the laboratory tests are less than that obtained from the field permeability tests,respectively.

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.
