Performance of a test embankment constructed on an organic clayey silt deposit
Bibliographic record
Abstract
The instrumentation, construction, and field performance of a full-scale test embankment constructed on a soft compressible organic clayey silt is described. The construction sequence, the observed vertical and horizontal displacements, and the pore pressure response are presented. The embankment behaved elastically up to a thickness of about 3.65 m. The settlement and heave responses suggested that the embankment approached failure at a thickness of about 6.1 m and a corresponding net height of 5.4 m. The failure was gradual and of a viscoplastic type, and no classical-type abrupt failure was encountered during the construction of this embankment. The height to which the embankment could be constructed was lower than the 711.4 m range expected from conventional two-dimensional (2D) limit equilibrium analysis based on vane strength data. This, coupled with the pore pressure response, suggests that a combination of progressive failure and the influence of the adjacent reinforced section constructed to failure may have been significant factors affecting the performance of this embankment. Thus, the data reported in this paper can be used as a test case for developing three- dimensional (3D) analysis methods wherein the constitutive model can be truly tested for 3D conditions involving the interaction between embankment sections that are constructed under different conditions.Key words: embankment, field behaviour, stability, deformations, pore pressures.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
