Fines-controlled drainage in just-saturated, inertial column collapses (2023)
Journal Article

The wide particle size distributions, over several orders of magnitude, observed in debris flows leads to a diverse range of rheological behaviours controlling flow outcomes. This study explores the influence of different scale grains by conducting s... Read More about Fines-controlled drainage in just-saturated, inertial column collapses.

The role of abrasion in cyclically sheared soil-structure interfaces (2023)

Pettey, A., & Heron, C. M. (2023). The role of abrasion in cyclically sheared soil-structure interfaces. Géotechnique, https://doi.org/10.1680/jgeot.22.00326

A limiting factor in the drive to deliver performance-based design is the lack of knowledge regarding the constitutive behaviour of soil-structure interfaces, particularly in the case of cyclic loading. A series of experiments were undertaken using b... Read More about The role of abrasion in cyclically sheared soil-structure interfaces.

Inertial effects in just-saturated axisymmetric column collapses (2023)

This work introduces a scaling analysis of sub-aerial axisymmetric column collapses of glass beads and Newtonian glycerol-water solutions mimicking some of the behaviours of debris flows. The beads were in a size range where their inertia partly deco... Read More about Inertial effects in just-saturated axisymmetric column collapses.

In many European countries, lignite or brown coal is used as a fuel source in steam-electric power generation. Upon completion of mining activities, a reclamation plan is imperative to ensure environmental and social prosperity of local areas. Abando...

Pit lakes are a common form of reclamation of areas where open pit mining activities have taken place. The development of these lakes often uses previous overburden materials, or “spoils”, that are readily available. Depending on the local geology, t...

The constitutive behavior of soil is stress dependent. Therefore, geotechnical centrifuges are widely used to replicate full-scale stress fields, thereby ensuring the correct soil response within reduced-scale centrifuge models. A vibration-absorbing...
