Abstract
Abstract Closed-form solutions are deduced in the present article for the stresses and displacements generated during installation of the flat dilatometer blade in undrained clay, by assuming that the soil behaves ideally elastic first and elastic-plastic second. In the first case, the installation of the dilatometer is modeled as the expansion of a long elliptical cavity, commencing from a vertical line crack under uniform internal pressure. Computations indicate that the horizontal tangential stress may reach very high negative or tensile values in areas located along the edges of the elliptical cavity. In these areas, the maximum shear stresses also attain very high levels. As a consequence, either fractures or plastic deformations would be expected to develop in such areas. In the second case, the installation of the dilatometer is modeled as the expansion of a long cylindrical cavity, in which the applied pressure is transmitted through an internal hydrostatic core. Outside the core, the clay behaves as a linearly elastic perfectly plastic (Tresca) material. The computed ultimate radial pressures compare well with published data obtained by means of finite element analyses. Finally, the theoretical solutions are applied to field tests carried out in a sensitive clay deposit of eastern Canada. The results show that the clay suffers severe remolding following the insertion of the dilatometer.

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.
