In this paper, a stratigraphic profiling approach is proposed based on the soil behavior type index, Ic, obtained from the cone penetration test (CPT). The basic idea of this approach is simple: the layer boundaries can be identified as the points at which a change occurs in the Ic profile. It is shown that these change points can be easily identified

Cone penetration test (CPT)-based soil behaviour type (SBT) classification system — an update
Canadian Geotechnical Journal, 2016A soil classification system is used to group soils according to shared qualities or characteristics based on simple cost-effective tests. The most common soil classification systems used in geotechnical engineering are based on physical (textural) characteristics such as grain size and plasticity.

Cone penetration test (CPT) data profile is often numerically modelled using random field theory and based implicitly on a fundamental assumption: statistical homogeneity of the preprocessed stationary CPT data profile. In classical random field theory, statistical homogeneity evaluation may only be achieved if the CPT data profile is infinite in ...

Machine Learning-Based Cone Penetration Test (CPT) Data Interpretation
AIJR Proceedings, 2023Ground investigations (GI) are essential prior to the design of construction projects. Among the different GI tasks, classifying soils into groups with similar properties is a fundamental geotechnical engineering process. Currently, experienced geotechnical engineers manually conduct soil classification using empirical tables based on laboratory or in ...

Prediction of pile shaft resistance using cone penetration tests (CPTs)
Computers and Geotechnics, 2012Abstract Accurately predicting pile shaft resistance when designing pile foundations is necessary for ensuring appropriate structural and serviceability performance. The scope of this research includes four main components: (I) compiling shaft resistance datasets obtained from the published literature; (II) developing two artificial neural network ...

Is the Cone Penetration Test (CPT) Useful for Arctic Site Investigation?
Volume 10: Polar and Arctic Science and Technology, 2014A warming Arctic provides increased opportunity for infrastructure development. Although the cone penetration test is used globally for site investigation in unfrozen soils, this discussion paper investigates the use of cone penetration testing to provide in situ data in frozen geomaterials.

Geostatistical analysis of cone penetration test (CPT) sounding using the modified Bartlett test
Canadian Geotechnical Journal, 2004More in situ tests are typically carried out over the same volume of soil in comparison to laboratory tests on undisturbed borehole samples. Hence, geostatistical analysis of in situ test records should in principle provide a more accurate and representative overview of spatial variation. A natural probabilistic model for correlated spatial data is the

New ultimate pile capacity prediction method based on cone penetration test (CPT)
Canadian Geotechnical Journal, 2012Our research evaluated current cone penetration test (CPT) pile design methodologies (Schmertmann, Laboratoire Central des Ponts et Chaussées (LCPC), etc.), modified one of these methods (Philipponnat method), and proposed a new one to improve future driven pile designs.

Semi-Empirical Method Interpretation of Cone Penetration Test (CPT) Data
Discovery and Innovation, 2001Cone Penetration Test (CPT) is a reliable technique for measuring subsurface soil friction, cohesion and bearing capacity for pile foundation. In some parts of the world the mechanical cone method is commonly employed and the mobilized cone tip resistance is representative.
