Research on the Working Performance of Dowel Bar during Horizontal Installation Errors
Bibliographic record
Abstract
Through the pullout test on dowel bar of different surface treatment modes and position deviation, the paper draws the conclusion that the plastic spraying treatment in different surface treatment modes can maximum meet the setting requirements of dowel bar, and the angular deviation of the dowel bar is the main reason for the cracking within the 50 centimeters of both sides of cement concrete pavement joint; Through the bending fatigue test, the paper evaluates the attenuation law of joint load transfer capacity under different horizontal installation error conditions(0°, 5°, 10° and 15°), and find that with the increase of dowel bar deviation angle, the initial joint load transfer capacity presents a rapid downward trend, and the performance of whole working period become worse and worse, when the angular deviation of dowel bar in the horizontal plane is not more than 5°, juncture load transfer capacity can still remain the medium level, which will not have too much influence on the working performance of dowel bar. Finally, the paper presents the looseness of dowel bar after 800,000 times of bending fatigue, and puts forward the control measures to avoid position deviation of dowel bar.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
