Abstract

fetched live from OpenAlex

To be able to properly analyse rapid load pile tests in clay soils (e.g., Statnamic) an understanding of the material’s behaviour at elevated shearing rates is required, as clays demonstrate nonlinear shearing resistance as the rate of shearing increases. To determine the relationship between pile resistance under static and elevated rates of loading, rate effect parameters for viscous damping have historically been derived from pile head measurements on full scale pile tests. These parameters are then attributed to a soil type with little recognition of what aspects of a soil may give further variation to them. To study this variation a test pile was installed in glacial till and instrumented with strain gauged sister bars at various levels down the pile shaft. Direct measurements of pile shaft resistance in both rapid load and static pile tests show that derivation of average parameters from pile head readings masks the variation in rate effect along a pile shaft. The variation of rate effects along the pile shaft is apparently linked to in situ moisture content.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
