A comparison of Advanced Constitutive Models to Evaluate Flow Liquefaction of Upstream Raised Tailings Dams

Mauro Giuliano Sottile - November 14, 2024

Presented by the winner of the “Bright Spark Award 2024”, this study uses a numerical procedure to assess the susceptibility of a typical upstream-raised TSF to flow liquefaction by applying undrained loads at the beach/berm of the dam and contractions at the starter dam.
