Nine-Year Field-Monitoring Data from an Integral-Abutment Bridge
Bibliographic record
Abstract
Many field studies of integral abutment bridges have focussed on construction and short-term behaviour, while the data on long-term performance are not abundant. In this paper, long-term field monitoring data from an instrumented integral abutment bridge in Fredericton, NB are presented. The primary objective is to add to the limited database of long-term monitoring so that the information might be used to calibrate numerical methods predicting long-term performance over the design life of a bridge. In this paper, data of abutment movements and earth pressures on the abutments over a 9-year monitoring period are presented. Field data indicate that the primary mode of movement for one abutment is translation and a combination of rotation and translation for the other abutment. Data also indicate that the abutments are tilting in opposite directions to one another, resulting in torsion of the bridge superstructure. Finally, of particular interest, is the concern of earth pressure ratcheting. Data do not conclusively show an increase in passive earth pressures behind the abutment over the 9-year monitoring period.

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.
