Abstract
Cable force of construction control and alignment control of main girders are key factors for long-span railway cable-stayed bridges. To make both stayed cable force and alignment of main girders under ideal state simultaneously during construction, based on first-order optimum algorithm, this article regards bending strain energy as an objective function, and then the initial tension can be known through iteration. After analyzing the impact of some factors on alignment control of main girders, such as initial tension of stayed cables and construction load, the formula of alignment control about main girders can be obtained. Finally, taking one of the world's largest railway cable-stayed bridges for an example, the article calculates the initial tension of stayed cables, and analyses the effects of some factors on alignment control of long-span railway cable-stayed bridges. It turns out that this method can keep the alignment and internal force of main girders reasonable.

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
