Abstract
This paper examines the potential for two-dimensional (2D) and three-dimensional (3D) finite element (FE) analyses to calculate the ground displacement patterns observed at a greenfield site above two recently completed tunnels in Perth, Western Australia. The influence of a range of different factors on the shape of the tunnelling-induced settlement trough is examined using the Plaxis FE code and three soil constitutive models. It is shown that while model input parameters can be varied to produce calculations that are more comparable to field observations, there remain considerable errors associated with modelling of the tunnelling procedure by the imposition of volumetric contractions at the tunnel location.

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
