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)
Journal Article

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)
Journal Article

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.

Characterisation of spoil materials to develop an equivalent spoil material for physical model tests (2022)
Journal Article

The engineering behaviour of spoil (overburden) needs to be explored either to understand the stability of reservoir slopes under various geological and climatic conditions or for the effective utilisation of reclaimed mines for sustainable infrastru...

Effect of spatial variation of spoil material properties on slope displacements under rapid drawndown of pit lakes (2022)
Journal Article

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...

Centrifuge modelling of spoil slopes within pit-lake mine reclamations (2022)
Journal Article

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...

Foundation systems for sustainable revitalisation of spoil dump areas (2022)
Journal Article

The design of foundations systems is well established in the literature and codes of practice. However, these are generally applicable to well characterised, homogenous ground conditions. Spoil materials represent a significant challenge when impleme... Read More about Foundation systems for sustainable revitalisation of spoil dump areas.

The challenges associated with laboratory scale physical modelling of high-plasticity spoil materials (2022)
Journal Article

Characterisation of spoil (surface mine overburden) material is essential when investigating geotechnical issues associated with the spoil, e.g., for investigating the stability of pit lakes formed with spoil or spoil-structure interaction for any st...

Closure to “Centrifuge Tests on Rock-Socketed Piles: Effect of Socket Roughness on Shaft Resistance” by J. G. Gutierrez-Ch, G. Song, C. M. Heron, A. Marshall, and R. Jimenez (2022)
Journal Article

Effect of Duxseal on Horizontal Stress and Soil Stiffness in Small-Amplitude Dynamic Centrifuge Models (2022)
Journal Article

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...

Centrifuge Tests on Rock-Socketed Piles: Effect of Socket Roughness on Shaft Resistance (2021)
Journal Article

Preliminary estimations of shaft resistance of rock-socketed piles are usually conducted using empirical formulations that relate to the uniaxial compressive strength (σc) of the weaker material involved (intact rock or pile). However, there are othe... Read More about Centrifuge Tests on Rock-Socketed Piles: Effect of Socket Roughness on Shaft Resistance.

Centrifuge application of fibre Bragg gratings: pile axial loads and wall bending moments (2021)
Journal Article

One challenge for geotechnical centrifuge testing of soil-structure interaction problems is the reliable measurement of induced structural strains/forces. This paper presents a novel application of fibre Bragg grating (FBG) sensors for strain measure...

Geocellular railway drainage systems: physical and numerical modelling (2019)
Journal Article

The importance of resilient railway infrastructure is paramount when considering the increased likelihood of extreme weather and flash flood events in coming years. One of the main causes of instability of railway tracks is excess water in the trackb... Read More about Geocellular railway drainage systems: physical and numerical modelling.

Stability and characterisation of spoil heaps in European surface lignite mines: a state-of-the-art review in light of new data (2019)
Journal Article

The large amount of spoil material produced during the mining process imposes a significant economic and environmental liability on lignite producers. In this context, the present paper provides an overview of the geotechnical characteristics of Euro...

Real-time data coupling for hybrid testing in a geotechnical centrifuge (2019)
Journal Article

Geotechnical centrifuge models necessarily involve simplifications compared to the full-scale scenario under investigation. In particular, structural systems (e.g. buildings or foundations) generally can’t be replicated such that complex full-scale c...

Analysis of particle contact using frustrated total internal reflection (2019)
Journal Article

Within the field of soil mechanics a continuum assumption is generally adopted in order to avoid the complications of modelling micro-mechanical behaviour. However, certain constitutive behaviour can only be explained by investigating particle level... Read More about Analysis of particle contact using frustrated total internal reflection.
