Characterization of Three-Dimensional Particle Shape for Rock Fragments in Embankment DAMS

Year: 2025

Type: conference-paper

Abstract: This study proposes a particle geometric morphology reconstruction method based on the theory of 3D vision measurement, specifically Structure from Motion-Multi-View Stereo (SfM-MVS), and has measured nearly 200 particles at a rockfill dam construction site. The analysis results show that both particles exhibit a pronounced size effect on the ratio of intermediate to longest axes (I/L), with smaller particles tending to adopt a narrower and more elongated shape. The change in sphericity for sand and gravel is more distinct compared to that of rockfill; smaller particles display lower average sphericity and more irregular shapes. However, the flatness (S/I) and angularity of the particles do not demonstrate significant size effects in the large-scale dam construction particles analyzed in this study.
