Performance of micropiled raft in clay subjected to vertical concentrated load: centrifuge modeling
Bibliographic record
Abstract
The overall behavior of a micropiled raft foundation (MPR) system is similar to a piled raft foundation where the load is transferred by both the raft and micropiles. However, there is no guidance available regarding the design of MPRs or indication of their performance. In this study, geotechnical centrifuge testing was conducted to investigate the behavior of MPR foundations in clay and evaluate their performance characteristics. The study evaluated the performance of MPRs compared to the isolated raft in terms of raft total and differential settlements; raft contact pressure; raft bending moment; and load sharing between the raft and the micropiles. The results showed that for the MPR configuration considered in the study, the raft carried 48% of the applied load. It was found that the Poulos–Davis–Randolph (PDR) method can be used to evaluate the performance of MPR for preliminarily design purposes with approximately 17% error.

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.
