Feasibility assessment of electro-osmotic consolidation on marine sediment
Bibliographic record
Abstract
A procedure is developed for the feasibility assessment of electro-osmotic (EO) consolidation of geomaterials, including fine-grained soils, sediments and mine tailings containing clay minerals. The assessment is based on a series of parametric studies to examine the effectiveness and efficiency of the electro-osmotic process in a site-specific geomaterial. The feasibility study on a natural marine sediment recovered from the seabed of the Korean coast is presented to illustrate steps involved in the assessment. In particular, the effects of soil pore fluid salinity and void ratio on electro-osmotic consolidation using intermittent current are examined. The results show that the effectiveness of electro-osmotic consolidation, assessed by the EO permeability ratio, increases when the soil void ratio decreases, whereas it is not significantly affected by the pore fluid salinity. The study also illustrates that the power consumption in an electro-osmotic consolidation process is predominantly controlled by the electrical conductivity of the soil, which is a function of the soil pore fluid salinity and void ratio. Une procédure est développée pour l'évaluation de la faisabilité de la consolidation électro-osmotique (EO) des géomatériaux incluant les sols granulaires fins, les sédiments et les résidus miniers. L'évaluation est basée sur une série d'études paramétriques pour examiner l'efficacité et l'efficience du processus électro-osmotique dans un géomatériau spécifique. On présente l'étude de l'efficacité sur sédiment marin naturel provenant d'un fond marin de la cote coréenne pour illustrer les é tapes comprises dans l'évaluation. On examine, en particulier, les effets de la salinité de l'eau interstitielle et de l'indice des vides sur la consolidation électro-osmotique en utilisant le courant intermittent. Les résultats montrent que l'efficacité consolidation électro-osmotique, évaluée par le rapport de permeéabilité EO, augmente quand l'indice des vides du sol décroît tandis qu'elle n'est pas affectée de façon significative par la salinité de l'eau interstitielle. L'étude illustre aussi que la consommation de puissance dans un processus de consolidation électro-osmotique est principalement contrôlée par la conductivité é lectrique du sol qui est une fonction salinité de l'eau interstitielle et de l'indice des vides.

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.
