Journal Article
Lloret-Cabot, M., Zhang, K., Zhang, W., Kourdey, A., & Hicks, M. A. (online). Quantifying the effects of vibro-compaction on soil heterogeneity and geotechnical uncertainty. Georisk: Assessment and Management of Risk for Engineered Systems and Geohazards, https://doi.org/10.1080/17499518.2025.2478636

Geological materials exhibit spatial variability in their properties as a result of their formation. Many studies have focussed on how to characterise this spatial variation by means of the correlation length θ. Such a characterisation has been appli...
