Abstract

fetched live from OpenAlex

Probabilistic analysis of failure problems in geomechanics is often directed towards assessing the mean and variance of design quantities (e.g. Factor of Safety, bearing capacity, limiting earth pressure) as a function of the mean and variance of input quantities (e.g. shear strength parameters). When spatial correlation length is also included as an input parameter, an additional complexity is introduced in that this parameter directly impacts the locally averaged shear strength along a failure surface. A key advantage of the Random Finite Element Method (RFEM) over conventional methods is that no a priori assumptions are made about the shape or location of the critical failure mechanism. The RFEM enables the mechanism to "seek out" the critical route leading to the minimum factor of safety. By forcing the mechanism to be circular (say), traditional approaches are inevitably "upper bound" and can lead to unconservative conclusions regarding slope failure risk.

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.

Not 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.
