A contact model able to capture creep of crushable sands within a discrete element method (DEM) framework is presented. Time dependency is established through stress-corrosion induced grain fracture. This is grafted onto a pre-existing particle-split

The mechanical response of natural soils is characterized by a narrow elastic domain, a smooth transition between elastic to elasto-plastic regime, and hysteretic behaviour during cyclic loading. These realistic features can be efficiently intro-duce

CPTu-based soil profiling has become a key component in the geotechnical design process. However, this is an interpretative process, affected by the inherent variability of soil properties, measurement noise and subjective heuristics. These are diffi

Static liquefaction of soils that have a brittle undrained response (hydraulic fills, mine tailings or sensitive clays) may lead to sudden failures of large consequence. Given the importance of undrained failure, obtaining precise estimates of peak a

Both static and dynamic penetration tests are widely used to conduct soil investigation practice. Particle crushability has been known to greatly affect the responses of penetration tests. On the other hand, the physical property of granular material

Disturbance of specimens recovered by tube sampling from boreholes is an enduring relevant problem in geotechnical engineering. Practice has evolved slowly in this area, partly because the main research method applied, involving comparative field sam

Flow liquefaction is a geotechnical hazard in mine tailings storage facilities. Susceptibility to liquefaction is typically evaluated with the CPTu by estimating the state parameter (¿). This parameter allows estimating the contractive or dilative b

The presence of potentially liquefiable deposits in tailing dams represents a serious hazard, as is now increasingly clear that liquefaction triggering may occur in unanticipated ways. For legacy dams in which this hazard is already present, interven

This paper illustrates how pressuremeter testing may add value to geotechnical characterization of tailing storage facilities (TSF). This is done with reference to results obtained in a campaign on jarosa, a lime-stabilized filtered jarosite residue
