Seepage of aging conduits in small reservoirs by centrifuge model test [PDF]
Scientific ReportsPiping is a critical failure mechanism in aging reservoirs, disrupting internal stress balance and threatening stability. In small agricultural reservoirs, aged conduits buried near the dam base are often undetected, allowing soil erosion through cracks ...

Centrifuge model tests on pile-reinforced slopes subjected to drawdown
Journal of Rock Mechanics and Geotechnical Engineering, 2020 Piles are generally an effective way to reduce the risk of slope failure. However, previous approaches for slope stability analysis did not consider the effect of the piles coupled with the decrease of the water level (drawdown).
