Abstract
To assess the seismic performance of soil-nailed walls, a series of 1g shaking table tests was conducted on 0.8 m high wall models with different nail lengths. It was found that the seismic deformation mode of walls highly depends on the nail length and input motion parameters. The combination of a base sliding and rotating deformation mode was observed as the predominant mode of deformation and the length to height (L/H) ratio of 0.7 was presented as the critical ratio in seismic conditions. The pattern of the observed failure mechanisms was similar to a third-degree polynomial failure surface with a specific inflection point. Irrespective of different nail lengths, the threshold acceleration corresponding to the onset of plastic displacements was similar and equal to 0.5g for all models. Based on the formation of initial cracks, a range of Δx/H = 0.33%–0.56% (where Δx is the lateral displacement of the facing) was found as a transitional level from quasi-elastic to plastic state. Also, based on the initial development of the active wedge failure, a range of Δx/H = 3.3%–4.3% was found as a transitional level from plastic to failure state.

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
