Abstract

fetched live from OpenAlex

This article describes a case history in which temporary segmental casings became trapped in a deep glacially overconsolidated soil. The segmental casings were used to construct 2.5 m diameter drilled shafts to depths up to 30–35 m along the alignment of an elevated transportation structure. Although the advancement of the casings and excavation went smoothly, in several circumstances the casings became stuck during extraction. This situation resulted in abandonment of the concrete placement operation and extensive subsequent work to recover the casings. A recognition of the ground conditions causing this situation led to the identification of locations that could have similar problems and the development of a workable solution. Analytical and numerical analyses were conducted to support the qualitative understanding of the problem and are also described.

Teacher imitation

Not 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.
