Model-based classification of CPT data and automated lithostratigraphic mapping for high-resolution characterization of a heterogeneous sedimentary aquifer

Abstract: Cone penetration testing (CPT) is one of the most efficient and versatile methods currently available for geotechnical, lithostratigraphic and hydrogeological site characterization. Currently available methods for soil behaviour type classification (SBT) of CPT data however have severe limitations, often restricting their application to a local scale. For parameterization of regional groundwater flow or geotechnical models, and delineation of regional hydro- or lithostratigraphy, regional SBT classification wo… Show more

“…In comparison to other methods of geotechnical investigation, CPTs are generally well suited for ML as they are (currently) one of the few geotechnical tests that aim at high resolution data acquisition and generate high quality and high quantity data. There have been several applications of supervised and unsupervised ML for different CPT‐related tasks (e.g., Goh, 1995; Kohestani, Hassanlourad, & Ardakani, 2015; Rogiers et al., 2017). See, for example, Carvalho and Ribeiro (2019) who use the two ML classification algorithms K‐nearest neighbors and distance weighted nearest neighbors to replicate the CPT classifications according to Robertson (2009, 2016) and provide a comprehensive list of papers related to CPT and ML.…”

“…Most work that use machine learning techniques for classifying soil from CPT data apply clustering to propose new soil classes (Hegazy & Mayne, 2002;Facciorusso & Uzielli, 2004;Bhattacharya & Solomtine, 2006;Liao & Mayne, 2007;Das & Basudhar, 2009;Rogiers et al, 2017;Wang et al, 2019). One limitation of these work is the reduced number of input features included, most times only two.…”

“…Another limitation is that most work explore only hierarchical clustering techniques (Hegazy & Mayne, 2002;Facciorusso & Uzielli, 2004;Bhattacharya & Solomtine, 2006;Liao & Mayne, 2007). Nevertheless, a recent study stated that including depth as an input can improve cluster-ing results and that the x-means algorithm can lead to good results (Rogiers et al, 2017). In spite of these conclusions, to the best knowledge of the authors, no work from the literature investigated clustering techniques including all measured CPT parameters.…”

“…For soil classification systems there are two main approaches, one is replicating existing soil classification systems and the other is trying to propose new ones. Most work in this research field are dedicated to the latter approach, using data clustering (Hegazy & Mayne, 2002;Facciorusso & Uzielli, 2004;Liao & Mayne, 2007;Das & Basudhar, 2009;Rogiers et al, 2017). Usually, among the few work that investigate replicating existing soil classification systems such as Robertson charts (Arel, 2012), the only ML technique tested is ANN (Kurup & Griffin, 2006;Reale et al, 2018).…”
