Grading curve relations for saturated hydraulic conductivity of granular materials (2024)
Journal Article
Imre, E., Illés, Z., Casini, F., Guida, G., Feng, S., Datcheva, M., Baille, W., Bálint, Á., Mwinken, D. K., Lorincz, J., Leak, J., & Barreto, D. (online). Grading curve relations for saturated hydraulic conductivity of granular materials. Environmental Geotechnics, https://doi.org/10.1680/jenge.23.00131

Estimation of hydraulic conductivity in soils is challenging. The primary aim of this study is to demonstrate that such predictions may be improved if grading curves are appropriately quantified and described, as well as by including density-related...

Using grain size distribution to estimate permeability (2024)
Presentation / Conference Contribution
Imre, E., Bálint, Á., Houng, D. T. Q., López, L. L., Répássy, L., Mwinken, D. K., Illés, Z., Datcheva, M., Baille, W., Barreto, D., Leak, J., & Feng, S. (2024, August). Using grain size distribution to estimate permeability. Presented at XVIII European Conference on Soil Mechanics and Geotechnical Engineering, Lisbon, Portugal

This study examines the saturated water permeability using samples of loose and dense 2-fraction coarse sand mixtures. Besides the non-normalised entropy variables some additional parameters like density, diameter descriptors are used to characterize...

Particle size distribution induced fabric effects on the onset and post liquefaction behaviours of soils (2024)
Presentation / Conference Contribution
Leak, J., & Barreto, D. (2024, August). Particle size distribution induced fabric effects on the onset and post liquefaction behaviours of soils. Presented at XVIII European Conference on Soil Mechanics and Geotechnical Engineering, Lisbon, Portugal

Liquefaction in soils is a detrimental phenomenon. Microscale behaviours and their influence on the macroscale response during and after the onset of liquefaction are not well understood. In particular, how contact behaviours effect macroscale proper... Read More about Particle size distribution induced fabric effects on the onset and post liquefaction behaviours of soils.

A Grading Entropy Review of PSD-Based Frost Susceptibility Criteria (2024)
Presentation / Conference Contribution
Leak, J., Barreto, D., Wright, C., Bernal Sanchez, J., & Imre, E. (2024, February). A Grading Entropy Review of PSD-Based Frost Susceptibility Criteria. Presented at Geo-Congress 2024, Vancouver, British Columbia

Particle size distribution (PSD) is recognised among geotechnical engineers as an informative soil descriptor, and often used to predict geomechanical behaviours. However, the effectiveness of PSD to characterise frost action is debatable. Existing c... Read More about A Grading Entropy Review of PSD-Based Frost Susceptibility Criteria.

Exploring the Use of Rock Flour for Sustainable Peat Stabilisation (2024)
Presentation / Conference Contribution
Bernal-Sanchez, J., Coll, J., Leak, J., & Barreto, D. (2024, February). Exploring the Use of Rock Flour for Sustainable Peat Stabilisation. Presented at Geo-Congress 2024, Vancouver, British Columbia, Canada

This paper aims to investigate the mechanical behaviour of peat stabilised with glacial rock flour for foundation construction. Peat, a natural organic soil, presents challenges for construction due to its high compressibility and low bearing capacit...
