Abstract
Previous laboratory studies have shown that the injection of a calcium chloride solution followed by the injection of a sodium silicate solution during electroosmosis is effective in strengthening soft silty clay. Very stiff cemented soil near the anodes is formed after the treatment. This paper presents the effectiveness of the process in the field. Nine electrodes were installed using two grid arrangements with electrode spacings of 2.0 m × 2.5 m and 2.0 m × 5.0 m. The test procedure is similar to those employed in the laboratory. Test results show that the soil surrounding the anodes (within a diameter of 50–60 cm) became very stiff and cemented due to the effect of cementation between the two chemical solutions and soil particles under the electric field. Except for the areas of stiff cemented soil, the undrained shear strength of the soil between electrodes was increased substantially. Polarity reversal after normal polarity did not produce favorable improvement effects in terms of undrained shear strength of the soil and treatment time.

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 it
