The role of abrasion in cyclically sheared soil-structure interfaces (2023)
Journal Article
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)
Journal Article
Webb, W., Heron, C., & Turnbull, B. (2023). Inertial effects in just-saturated axisymmetric column collapses. Granular Matter, 25(2), Article 40. https://doi.org/10.1007/s10035-023-01326-x

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.

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.

Geocellular railway drainage systems: physical and numerical modelling (2019)
Journal Article
Tasalloti, A., Marshall, A. M., Heron, C. M., & Hashemi, M. A. (2020). Geocellular railway drainage systems: physical and numerical modelling. Transportation Geotechnics, 22, 1-12

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.

Calibration of strain gauged square tunnels for centrifuge testing (2016)
Journal Article
Tsinidis, G., Heron, C., Madabhushi, G., & Pitilakis, K. (in press). Calibration of strain gauged square tunnels for centrifuge testing. Geotechnical and Geological Engineering, 34(3), https://doi.org/10.1007/s10706-016-0015-9

A series of dynamic centrifuge tests were conducted on square aluminum model tunnels embedded in dry sand. The tests were carried out at the Schofield Centre of the Cambridge University Engineering Department, aiming to investigate the dynamic respon...

A new macro-element model encapsulating the dynamic moment-rotation behaviour of raft foundations (2015)
Journal Article
Heron, C., Haigh, S., & Madabhushi, S. (2015). A new macro-element model encapsulating the dynamic moment-rotation behaviour of raft foundations. Géotechnique, 65(5), https://doi.org/10.1680/geot.SIP.15.P.020

The interaction of shallow foundations with the underlying soil during dynamic loading can have both positive and negative effects on the behaviour of the superstructure. Although the negative impacts are generally considered within design codes, sel... Read More about A new macro-element model encapsulating the dynamic moment-rotation behaviour of raft foundations.

Imaging the failure of a rock-fill dam following liquefaction (2013)
Journal Article

Rock-fill dams are popular in developing countries due to their ease of construction and use of local materials. They are used to store water and to provide flood defences. The presence of such dams in earthquake-prone regions poses risks, particular... Read More about Imaging the failure of a rock-fill dam following liquefaction.
