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 […]
Dr. Quentin Shaw Vice President of ICOLD – AFRICA and Henry-John Wright, newly elected Chairman of SANCOLD – SOUTH AFRICA representing ARQ Consulting Engineers at ICOLD 2023 in Sweden. ARQ Consulting Engineers is also celebrating their 3oth Year as International Civil Consulting Engineers in 2023.
The reservoir impoundment of the Yusufeli Dam has commenced in November 2022. ARQ is undertaking an impoundment safety study which comprises comparing the progressive behaviour of the dam and foundation during filling, to the anticipated behaviour as modelled by the results of FE analyses.
Foreword From the Chairperson of the South African National Committee on Large Dams(SANCOLD) On behalf of SANCOLD, I am pleased to welcome you all to the 2022 Annual Conference at TheRadisson Convention Centre, OR Tambo. We are very happy to have the opportunity to host this eventand to facilitate discussion and the exchange of knowledge […]
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 […]
