A note on seismic induced liquefaction (2019)
Presentation / Conference Contribution
Imre, E., Lőrincz, J., Trang, P., Barreto, D., Goudarzy, M., Rahemi, N., …Singh, V. (2019). A note on seismic induced liquefaction. In XVII European Conference on Soil Mechanics and Geotechnical Engineering: Conference proceedings. https://doi.org/10.

Any particle size distribution can be characterized by two parameter pairs (derived from the statistical entropy formula of discrete distributions) more effectively than simple diameter values (i.e., d50). The first entropy parameter is a conti... Read More about A note on seismic induced liquefaction.

X-ray tomography of sand-rubber mixtures (2019)
Presentation / Conference Contribution
Fonseca, J., Riaz, A., & Barreto, D. (2019). X-ray tomography of sand-rubber mixtures. In International Conference on Tomography of Materials and Structures Australia

The behavior of sand-rubber mixtures is controlled by the mechanisms taking place at the grain scale. Here, we use a mixture of shredded tire and a silica sand with similar grain sizes to investigate granular behavior under one-dimensional compressio...

Experimental assessment of stiffness and damping in rubber-sand mixtures at various strain levels (2019)
Presentation / Conference Contribution
Bernal-Sanchez, J., Mcdougall, J., Barreto, D., Marinelli, A., Dimitriadi, V., Anbazhagan, P., & Miranda, M. (2019, June). Experimental assessment of stiffness and damping in rubber-sand mixtures at various strain levels. Presented at 7th International Co

The dynamic properties of shredded rubber-soil mixtures (ShRm), comprising a sub-rounded quartz sand combined with small rubber shreds at 0, 10, 20, 30% by mass, were investigated. Testing ranged from small strain, in resonant column apparatus, to la... Read More about Experimental assessment of stiffness and damping in rubber-sand mixtures at various strain levels.

The geoengineering approach to the study of rivers and reservoirs (2019)
Journal Article
Corbett, P. W., Owen, A., Hartley, A., Pla-Pueyo, S., Barreto Gonzalez, D., Hackney, C., & Kape, S. (2019). The geoengineering approach to the study of rivers and reservoirs. Geological Society Special Publications, https://doi.org/10.1144/SP488-2018-98

This volume contains contributions for two meetings held to explore the links between geoscience and engineering in rivers and reservoirs (surface and subsurface). The first meeting was held in Brazil and as a result the volume contains many contrib... Read More about The geoengineering approach to the study of rivers and reservoirs.

Particle-scale interaction in sand-rubber mixtures and their influence on energy dissipation mechanisms (2019)
Journal Article
Fonseca, J., Riaz, A., Bernal-Sanchez, J., Barreto Gonzalez, D., McDougall, J., Miranda Manzanares, M., …Dimitriadi, V. (2019). Particle-scale interaction in sand-rubber mixtures and their influence on energy dissipation mechanisms. Géotechnique Letter

Sand-rubber mixture (SRm) behaviour is affected by rubber content (RC) whilst dissipation in sands is caused by inter-particle sliding. Dissipation in SRm is as, or more significant than in sands. However, the mechanisms of dissipation in SRm are not... Read More about Particle-scale interaction in sand-rubber mixtures and their influence on energy dissipation mechanisms.

Particle loss: An initial investigation into size effects and stress-dilatancy (2019)
Journal Article
McDougall, J., Kelly, D., & Daniel, B. (2019). Particle loss: An initial investigation into size effects and stress-dilatancy. Soils and Foundations, https://doi.org/10.1016/j.sandf.2019.03.002

Drained triaxial tests have been performed to explore the effect of particle loss on shearing behaviour and critical states in granular mixtures. The mixtures comprise Leighton Buzzard sand (d50 = 0.8 mm), to which was added 15% by mass of salt parti...

Dynamic behaviour of shredded rubber soil mixtures (2018)
Presentation / Conference Contribution
Bernal-Sanchez, J., McDougall, J., Barreto Gonzalez, D., Miranda, M., & Marinelli, A. (2018, June). Dynamic behaviour of shredded rubber soil mixtures. Presented at 16th European Conference on Earthquake Engineering, Thessaloniki

Residential buildings in high population density areas are seismically vulnerable to the action of major seismic events. The high cost and technical difficulties related to the use of advanced seismic isolations systems precludes its installation to...

Optical Fiber Sensor Design for Ground Slope Movement Monitoring for Railway Safety Operations (2018)
Presentation / Conference Contribution
Hook, D., Laing, W., Kerrouche, A., Barreto Gonzalez, D., & Alwis, L. S. (2018). Optical Fiber Sensor Design for Ground Slope Movement Monitoring for Railway Safety Operations. In 2018 IEEE Sensors Proceedings (1-4). https://doi.org/10.1109/ICSENS.2018.8

Scour and slope instability are a major issue in keeping the railway structures safe and operational. Conventional measurement techniques do not allow real-time monitoring of slope movement and/or are time/resource consuming. Novel fiber optic techno...
