Abstract
The cavity expansion theory has been widely used in geotechnical engineering.A modified critical state model is employed to account for the three different modes of compressive deformation,i.e.,particle rearrangement,particle crushing and pseudoelastic deformation.In combination with the spatial mobilization plane(SMP) failure criterion and non-associated flow rule,the semi-analytical solutions are obtained to expansion in crushable sands by using the Matlab differential equation solver.In comparison to those solutions where a conventional critical state line is used,the results obtained for Quebec sand indicate that particle crushing does occur at high stress and critical states and affects the stress fields surrounding the cavity and the deformation behaviour.This leads to conclusion that particle crushing has to be taken in account when the cavity expansion theory is used to interpret cone penetration tests and pressuremeter tests.

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
