Li, Yajun (author), Li, Jianguang (author), Xu, Nengxiong (author), Fenton, Gordon A. (author), Vardon, P.J. (author), Hicks, M.A. (author)Correlation length or scale of fluctuation (SOF) is often used as a primary parameter in defining the spatial correlation characteristics of varying soil properties. However, geotechnical site investigations are rather limited so that proper determination of correlation length is not always possible. The concept of a worst-case correlation...journal article 2022

Technical feasibility of a Dutch radioactive waste repository in Boom Clay: Geomechanical validationLi, Y. (author), Vardon, P.J. (author), Hicks, M.A. (author), Hart, Jaap (author), Fokker, Peter A. (author)OPERA-PU-TUD321d<br/>Radioactive substances and ionizing radiation are used in medicine, industry, agriculture, re- search, education and electricity production. This generates radioactive waste. In the Netherlands, this waste is collected, treated and stored by COVRA (Centrale Organisatie Voor Radioactief Afval). After interim storage for a...report 2018

Vardon, P.J. (author), Liu, K. (author), Hicks, M.A. (author)The determination of slope stability for existing slopes is challenging, partly due to the spatial variability of soils. Reliability-based design can incorporate uncertainties and yield probabilities of slope failure. Field measurements can be utilised to constrain probabilistic analyses, thereby reducing uncertainties and generally reducing...journal article 2016

Li, Y. (author), Hicks, M.A. (author), Vardon, P.J. (author)Long slopes with variable material properties have a variety of different failure modes that are affected by the correlation distances of the material properties and the geometry and total length of the slope. This work follows previous research examining the consequences of increasing slope length, in which analyses were limited by the...conference paper 2015
