Treatment of Collapsible Soils by Salts Using the Double Consolidation Method
Bibliographic record
Abstract
Collapsible soils are unsaturated soils which present a potential for large deformation and a complete change to the whole particle structure after wetting, with or without loading. These soils are characterized with loose structures composed of silt to fine-sand-size particles. Collapsible soils are deposited in arid and semi-arid regions. Due to the expansion of human activities, these regions are occupied aggressively leading to the use of large quantities of water, which creates favorable conditions for soil collapses. Theses soil failures lead to severe damage and large distress to man-made structures. The objective of this experimental study is to illustrate that the mechanical resistance of collapsible soil can be improved. This study demonstrates that it is possible to minimize the collapse potential Cp to an acceptable level after chemical treatment with salts (ammonium sulfates (NH4)2SO4 and potassium chlorides KC1) at different concentrations (i.e., 0.5, 1.0, 1.5 and 2.0 mole/liter) and under different compaction energies. The method used in this study is based on oedometric tests with variable normal stresses.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
