New apparatus improves testing for seepage and internal erosion in geotechnical centrifuge, indicating hypergravity effects.

CASIE ensures stable water supply of 34,000 ml/min at hypergravity of 80 g, enhancing test reliability.
Tests reveal that suffusion failure is more likely under hypergravity, with a critical hydraulic gradient scaling of 1/10.
Hydraulic gradients can be controlled via a servo lifting system with a maximum vertical speed of 155 mm/min.
The apparatus allows for versatile soil column testing, with flowrates easily measured across a range of 10–10,000 ml/min.

Guo et al. (2025) studied this question.
