Abstract

fetched live from OpenAlex

The observational approach is utilised when the prediction of geotechnical behaviour is challenging. The main principle of the observational approach is reviewing the design during construction after discovering that it is inadequate. Design modification decisions must be appropriately justified to prevent over-reliance on the engineer’s judgement. This could be achievable by predicting the effects of any potential design modifications in advance. This thesis investigates the observational approach from a probabilistic perspective in evaluating design options. For this purpose, a probabilistic convergence-confinement model is established for a tunnel design scenario that requires modification. In addition, a probabilistic traffic light system which quantifies the risks associated with each observation is developed. It is concluded that the suggested procedure can help assess support design options for various ground conditions.

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.
