Abstract
Juancheng Yellow River Highway Bridge is the largest externally pre-stressed concrete continuous box-girder bridge with corrugated steel webs in the world with the total length of 1460m and span arrangement of 70m+11×120m+70m. Based on the monitoring practice for this bridge construction, the paper illustrates the application of the two modeling methods for box-girder with corrugated steel webs in the calculation of alignment control using bridge analysis system GQJS, i.e. the one-node method and two-node method. Additionally, the comparison between the measured and predicted deformation under different construction stages including cantilever construction, closure construction, system transformation and external prestress tension is presented and discussed. The results turn out both the two proposed modeling methods can perfectly meet the requirements of alignment control of this kind of bridge.

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 it
