By Ryan Cassells, ARQ Dams co-author dr. Quentin Shaw IMIESA Publication September 2023 The fifth highest double curvature arch dam in the world, and the ninth highest dam globally, Yusufeli Dam is a landmark engineering achievement and cost US$711 million to construct. The ARQ-Su Yapi team for the dam design was led by Dr Quentin […]
ARQ recently performed advanced numerical modelling, employing critical state soil mechanics constitutive models, in support of a paper authored by John Wates which investigates the failure of the Brumadinho TSF. The mechanism of failure postulated in the work involves progressive failure triggered by the collapse of an internal void within the TSF, originally created by […]
By Michelle Blaeser – ARQ Dams at the SANCOLD 2022 ANNUAL CONFERENCE – Whereas design foundation criteria call for minimum values of various parameters including the Rock Mass Rating, RMR, Uniaxial Compressive Strength, UCS, weathering etc., sliding on potential sub-horizontal joint planes in the foundation was established to be the critical failure mode at Ntsonyini […]
By RO Cassells – ARQ Dams QHW Shaw , ARQ Consulting ARQ Dams, Pretoria, South Africa ARQ Consulting, Mauritius at the SANCOLD 2022 ANNUAL CONFERENCE – The Finite Element (FE) Method has been accepted by dam designers as the modern-day state-of-the-art approach for the structural analysis of large concrete arch dams, largely replacing previous approaches […]
by ARQ Geotech- Katy O’Brien, Thomas O’Brien & BRT Beric Robinson CivilEngineeringSaice/Vol30No3April 2022 Over the last few decades, design requirements for tailings storage facilities (TSFs) have become more elaborate and demanding. A critical state approach shows much merit as a tool to aid in assessing liquefaction trigger mechanisms. CONCLUSION Realistic assessment of TSF stability beyond […]
