Conference Proceeding
Tang, C., Marshall, A. M., Heron, C. M., Franza, A., & Xu, J. (in press). Setup and calibration of piles with FBG strain sensors in a geotechnical centrifuge = Configuration et calibration de pieux équipés de capteurs de deformation FBG dans une centrifugeuse géotechnique. In Proceedings of the XVIII ECSMGE 2024

This paper discusses technical aspects of the experimental setup and calibration processing during centrifuge testing of single piles, instrumented with fibre Bragg grating (FBG) strain sensors, under vertical loads. Results illustrate the influence...

Implementation of real contact behaviour in the DEM modelling of triaxial tests on railway ballast (2022)
Journal Article
Tolomeo, M., & McDowell, G. R. (2022). Implementation of real contact behaviour in the DEM modelling of triaxial tests on railway ballast. Powder Technology, 412, Article 118021. https://doi.org/10.1016/j.powtec.2022.118021

In the Discrete Element modelling of soils, the micromechanical behaviour at contacts has often been considered to have a minor influence on the macromechanical response, leaving basic theoretical models (e.g., Hertz) to describe the contact response...

Modelling real particle shape in DEM: a comparison of two methods with application to railway ballast (2022)
Journal Article
Tolomeo, M., & McDowell, G. R. (2022). Modelling real particle shape in DEM: a comparison of two methods with application to railway ballast. International Journal of Rock Mechanics and Mining Sciences, 159, Article 105221. https://doi.org/10.1016/j.ijrmms.2022.105221

Two different methods for the modelling of real particle shape in 3D DEM simulations are assessed in this paper. The first method uses overlapping spheres (clumps), while the second uses a block defined as a closed and convex polyhedron. The two meth...

Numerical Analysis of the Settlement Behavior of Soft Soil Improved with Stone Columns (2022)
Journal Article
Grizi, A., Al-Ani, W., & Wanatowski, D. (2022). Numerical Analysis of the Settlement Behavior of Soft Soil Improved with Stone Columns. Applied Sciences, 12(11), Article 5293. https://doi.org/10.3390/app12115293

The use of column-like elements for improving both the settlement performance and bearing capacity of foundations constructed over soft soils is well understood for large groups of columns supporting an infinitely wide load, such as embankments and s...

Empirical and semi-analytical methods for evaluating tunnelling-induced ground movements in sands (2019)
Journal Article
Franza, A., & Marshall, A. M. (2019). Empirical and semi-analytical methods for evaluating tunnelling-induced ground movements in sands. Tunnelling and Underground Space Technology, 88, 47-62. https://doi.org/10.1016/j.tust.2019.02.016

Empirical formulas and closed-form solutions provide, in many cases, good predictions of tunnelling-induced ground movements which, when combined with their computational efficiency, make them valuable for tunnel-structure interaction analyses. For s... Read More about Empirical and semi-analytical methods for evaluating tunnelling-induced ground movements in sands.
