A parametric study on the stability of tailings storage facilities with cemented berms Open
A parametric study using the limit equilibrium method was carried out to evaluate the influence of a berm of cemented tailings on the stability conditions of dry stack tailings storage facilities over different water table configurations. …

The variation of large strain viscous rate effects from undrained triaxial element testing of Kaolin clay Open
Viscous (undrained) rate effects lead to an increase in the shear strength of fine-grained soils such as clays when sheared at high strain rates. Correct rate effect parameters are key to accurate predictions of behaviour in a range of geo…

Ice loss detection of glacierets in the Desert and Central Andes of Chile between 2018 and 2023 Open
Worldwide, the shrinkage of small glaciers has occurred more rapidly in recent decades, and the Desert and Central Andes of Chile are no exception. Among these ice bodies are glacierets, defined as glaciers with a reduced surface area of l…

Discrete Modelling of Breakage Induced Pile Creep in a Centrifuge Open
Time-dependent pile settlement under sustained service load has been reported in the literature and was defined as pile creep. Particle breakage has been found as the main mechanism for pile creep in sand by Leung et al., [1]. Based on the…

Stress field on intermediate length scales during triaxial compression Open
Defining a continuum stress field in a granular medium involves an approximation, as the underlying contact force network between particles is inhomogeneous and random. The continuum approximation introduces some baseline noise or variabil…

View article: A fracture-based discrete model for simulating creep in quartz sands
A fracture-based discrete model for simulating creep in quartz sands Open
Creep of granular soils is frequently accompanied by grain breakage. Stress corrosion driven grain breakage offers a micromechanically based explanation for granular creep. This study incorporates that concept into a new model based on the…

Sand and silt treatment with novel binders Open
An attractive approach to reduce the carbon footprint for ground improvement application is to replace Portland cementbased binders by non-cementitious binders for instance by geopolymers based on metakaolin in deep soil mixing application…

Numerical simulation of soil structure damage upon sampling Open
Sampling disturbance is a perennial problem of geotechnical site investigation. The structure of soft soils is particularly fragile and prone to disturbance during sampling. The extent by which different sampling procedures modify soil str…
