Performance of two cast-in-place box culverts under high embankments
Bibliographic record
Abstract
Two cast-in-place reinforced concrete box culverts (Longs Creek and McBean Brook culverts) with similar geometry were instrumented to monitor earth pressures. The Longs Creek structure is a 7.30 m wide by 4.53 m high double-cell box under 14.10 m of fill, constructed using the positive projection installation (PPI) method. The McBean Brook structure is a 6.75 m wide by 4.65 m high double-cell box culvert under 25.10 m of fill, constructed using the induced trench installation (ITI) method. Earth pressures were monitored as the fill height above the culvert was increased for both structures. Data from the McBean Brook culvert at a fill height of 14.40 m are compared with the data from the Longs Creek culvert. The similar geometries of these two prototype culverts provide a unique opportunity to compare their performance based on the two different installation methods. For a comparable height of soil cover, measured vertical earth pressures on the roofs were 0.94 and 0.56 times the overburden pressures for ...

How this classification was reachedexpand
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.
