Dynamic response characteristics of airport pavement foundations under aircraft taxiing loads
Bibliographic record
Abstract
In this study, the dynamic response characteristics of the upper roadbed of Kunming Changshui Airport Metro Line 6 Tunnel (burial depth of 10.5m) under B777-300ER and B767-300 aircraft taxiing load (40m/s) were analyzed by establishing a 3D finite element model. The results show that the peak vertical displacement (25.37mm) caused by the B777-300ER is 3.76 times that of the B767-300 (6.74mm), the peak dynamic stress is 2.1 times, and the depth of influence (6.26m) is 1.47 times that of the B767-300; the displacement and stress of the shallow roadbed show an inverted pot-bottom distribution, while the deeper one shows a linear decay; the acceleration response shows a symmetric and exponential decay, with the depth of influence reaching 8.94m (6.26m), and the acceleration response shows a symmetric exponential decay. The symmetric exponential decay of the acceleration response, with a depth of influence of 8.94m (threshold 0.1m/s²), suggests that the acceleration index should be prioritized to evaluate the dynamic response. The study provides a theoretical basis for the vibration reduction design of airport-metro co-located facilities.

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.
