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.

A Proposal to Standardize Vulnerability Analyses of Flow Liquefaction of Tailings Dams

Alejo Sfriso, Mauro Giuliano Sottile, Ariel Terlisky , Felipe López Rivarola, Arcesio Lizcano, Osvaldo Ledesma - November 14, 2024

Following the implementation of the GISTM guideline (ICMM 2020) the team at SRK has produced assessments of the vulnerability of tailings dams to flow liquefaction using numerical methods in mines around the world. This paper outlines a proposed procedure based on our experience.
