Centrifuge modelling of ground vibrations mitigation by inclined geofoam barrier
Bibliographic record
Abstract
This paper presents a centrifuge study on the performance of inclined geofoam barriers compared to a vertical geofoam barrier for the mitigation of ground vibrations induced by high-speed railways. Three different barrier inclinations (60°, 90° and 120°) are used in three centrifuge models. Each centrifuge model is tested for seven different frequencies. Therefore, the results of 21 centrifuge tests are reported in this paper. The results show that the barrier efficiency (BE) of inclined barriers is greater than the vertical BE for the points located behind the barrier. However, for a point located before the barrier, the BE reduces by using inclined barriers instead of the vertical barrier. The results also illustrate that the barrier efficiencies for the two inclined barriers used in this research, which have supplementary angles, are almost the same.

How this classification was reachedexpand
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.
