Infiltration into an embankment reinforced by nonwoven geotextiles
Bibliographic record
Abstract
The hydraulic behaviour of permeable geosynthetics within unsaturated embankments subjected to infiltration is examined using the finite element method. The van Genuchten Mualem model is employed to evaluate unsaturated hydraulic characteristics for both the soil and nonwoven geotextile. Using pore-water pressures obtained from the finite element analysis, stability analyses are conducted for the embankments, and the contribution of the nonwoven geo textile to stability is evaluated with reference to the observed performance of instrumented embankments. A numerical study is also conducted to examine the effect of geotextile configuration on the performance of reinforced embankments subject to infiltration. This study shows that nonwoven geotextiles may retard water flow in situations where the pore pressure is negative, whereas they act as a drainage material in situations where pore pressures are positive. It is also shown that the contribution of the nonwoven geotextile to the stability of the embankment as a drainage material is much less substantial than its role as a reinforcing material.Key words: nonwoven geotextile, drainage, unsaturated, embankment, stability.

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.
