Abstract
The temporary bridge is used to cross river, canyon, ditches and other obstacles duo to its simplicity, convenience for operation and short construction time.How to design the temporary bridge economically and install it quickly are the primary considerations to meet the load requirements and traffic considerations. Based on the structural optimization design theory, the Small Arch Bridge, which is a steel-concrete composite girder bridge and locates in Fu ling district of Chongqing city, is optimized using the linear programming method. In this method, first assume the cross-section of I-girder and the dimensions of deck as the design variables, the mechanical behavior of the whole bridge and the deformation stiffness as the constraints, and then find the minimized cost using MATLAB optimization tools. On the basis of the optimization results, this paper presented the arguments of I-girder and deck panel which meet the mechanical and economical requirements and could provide some references for bridges of like.

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
