Abstract
Abstract The mechanical status of longitudinal joints in shield tunnel during operation is an important index for structural evaluation. For most of the tunnels that are not pre‐embedded with monitoring elements, only a few indicators can be measured directly during daily inspections. To comprehensively evaluate the deformation and mechanical status of the tunnel, an inversion model of the longitudinal joints, which is based on the measured convergence deformation of the shield tunnel, is proposed. First, the joint rotation deformation is determined using the successive rotation method. Then, the internal force of the joint is obtained based on the joint deformation. The two steps of the model are coupled with the iterative process for obtaining the accurate position of the joint neutral axis. The proposed model is verified by full‐scale ring test. It provides a new approach for obtaining the tunnel mechanical status and thus lays a theoretical foundation for decision‐making with regard to tunnel maintenance.

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
