Dewatering Structures in High Water Content Materials
Bibliographic record
Abstract
This paper describes the behaviour of soft soils created by the rapid deposition of a sediment slurry and the mechanisms by which pore fluid escapes from the consolidating bed. Such rapid deposition occurs as a result of dumping dredge spoils at sea or in the case of disposing of mine tailings in settling ponds. Soft soils may experience a variety of natural deformations during consolidation. Consolidation-related structures are commonly observed in settling column experiments, geotechnical centrifuge tests and in the field. This paper deals with the specific class of soft-sediment intrusive and extrusive dewatering structures called respectively pillars and boils (or sediment volcanoes) that form spontaneously through self-weight consolidation. Dewatering structures were formed during self-weight consolidation centrifuge experiments of a naturally-occurring marine sediment under the influence of high “g” conditions. A description of the phenomenon is given, describing the geometry and nature of the dewatering structures observed, and highlights some of the soil physical properties and depositional conditions which appear to control the formation of the structures. This phenomenon is believed to have relevance to dredge spoil and mine tailing disposal, and to the safe handling and disposal of polluted high water content soil like wastes.

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.
