Establishing a Relationship between Particle size distribution & Thaw weakening Susceptibility in Soils (2025)
Journal Article
Leak, J., Dimitriadi, V., Barreto, D., Bernal-Sanchez, J., & Imre, E. (2025). Establishing a Relationship between Particle size distribution & Thaw weakening Susceptibility in Soils. Cold Regions Science and Technology, 231, Article 104423. https://doi.org/10.1016/j.coldregions.2025.104423

Susceptibility to frost action in soils is an important consideration in cold and seasonably cold regions. Whilst the particle size distribution (PSD) is commonly used to measure susceptibility to frost action, this method is typically seen as unreli...

This study presents a Geotechnical Seismic Isolation (GSI) system proposed for utilising Rubber-Soil mixtures (RSm) to enhance the dynamic performance of a modified soil and foundation structure. The inclusion of RSm enables the system to exhibit low... Read More about An Innovative Approach to Geotechnical Seismic Isolation: Rubber-Soil Mixture Trenches.

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 Conference on Geotechnical Earthquake Engineering, Rome

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.

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., Marinelli, A., & Dimitriadi, V. (2019). Particle-scale interaction in sand-rubber mixtures and their influence on energy dissipation mechanisms. Géotechnique Letters, 9(4), 1-6. https://doi.org/10.1680/jgele.18.00221

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.

Seismic liquefaction performance of strip foundations: Effect of ground improvement dimensions (2017)
Journal Article

Seismic performance of strip foundations on liquefiable soils with a permeable crust (2017)
Journal Article

Modern seismic codes dictate that the use of shallow foundations on liquefiable soils may be considered only after appropriate ground improvement. No further instructions are given regarding the improvement depth, or what changes if the surface layer...
