A simplified procedure to numerically evaluate triggering of static liquefaction in upstream-raised tailings storage facilities
M. G. Sottile, I. A. Cueto, A. O. Sfriso
The interest of the mining industry on the assessment of tailings static liquefaction has exacerbated after recent failures of upstream-raised tailings storage facilities (TSF). St…
A Family of Constitutive Models Implemented in PLAXIS to Simulate Cemented Mine Backfill
M. G. Sottile, N. A. Labanda, I. Garcia Mendive +2
A family of constitutive models for mine cemented backfill is presented. Four formulas for the density- and pressure-dependency of elastic moduli, five formulas for the density- an…
Stability assessment of a tailings storage facility using a non-local constitutive model accounting for anisotropic strain-softening
M. G. Sottile, N. A. Labanda, A. Kerguelén +2
Recent failures of upstream-raised tailings storage facilities (TSF) raised con-cerns on the future use of these dams. While being cost-effective, they entail higher risks than con…
Screening of seismic records to perform time-history dynamic analyses of tailings dams: a power-spectral based approach
N. A. Labanda, M. G. Sottile, I. A. Cueto +1
Time-history deformation analyses of upstream-raised tailings dams use seismic records as input data. Such records must be representative of the in-situ seismicity in terms of a wi…
A risk assessment of downdrag induced by reconsolidation of clays after upwards pipe jacking
N. A. Labanda, A. O. Sfriso, D. Tsingas +2
Salini-Impregilo is building part of the largest sanitary sewer system in the history of Argentina in the suburbs of Buenos Aires City, to serve a population of almost five million…
EPB-TBM tunnel under internal pressure: Assessment of serviceability
N. A. Labanda, A. O. Sfriso, D. Tsingas +2
The Mantanza-Riachuelo basin recovery is one of the most ambitious environmental projects under construction in Argentina. In this context, the sanitary bureau of the metropolitan…
