Seismic Liquefaction Potential Assessment by Means of Automated Numerical Modelling

Mauro Sottile, Alejo Sfriso, Nicolás Tasso

In this paper, an extensive numerical modelling exercise is performed to determine which are the main aspects of the soil and the earthquakes that control the liquefaction phenomenon and understand why these methods work so well.

Evaluation of the Triggering of Static Liquefaction of Tailings Dams Considering the SWCC

Felipe Lopez Rivarola, Mauro Sottile, Alejo Sfriso, Nicolás Tasso, Kevin Bernardo

Dive into the assessment of static liquefaction triggering in tailings dams and understand the role that the soil water characteristic curve (SWCC) plays.

Stability Analysis of Tailings Storage Facilities Using a Simplified Quasi-1D Deformation Model

Felipe Lopez Rivarola, Alejo Sfriso, Kevin Bernardo

This paper describes a simplified procedure to analyse the stability of tailings storage facilities at screening level, employing a quasi-1D FEM model. NorSand critical state constitutive model was employed.

Closure Cost Estimate — an Approach to Estimate Productivities of Main Closure Activities

Marco Espezua, Erick Vasquez

In this document, we use real data from a local experience for haul road closures. We propose an alternative method to estimate closure costs for an earthmoving group that contemplates a base work crew and base construction equipment to calculate key productivity.
