Investigation of piezocone dissipation test interpretation in clay accounting for vertical and horizontal porewater pressure dissipation with a large deformation axisymmetric penetration model

Frontiers in Built Environment
The piezocone (CPTu) dissipation test is used to characterize how the applied load from the penetrating cone is distributed between the soil and pore fluid during both penetrometer advancement and when penetration is paused.

Use of functional cluster analysis of CPTU data for assessment of a subsoil rigidity

Studia Geotechnica et Mechanica, 2018
This paper shows an example of the grouping of piezocone penetration test (CPTU) characteristics using functional data analysis, together with the results of clustering, in the form of a subsoil rigidity model.

Utökad utvärdering av CPTu-resultat

, 2022
In Sweden, it is common to use the CPT - Cone Penetration Test when probing in loose soils. This is mainly because the method is suitable for further assessment of soil layer sequences, pore pressure and forming an estimate of the geotechnical properties in-situ.

Evaluation of the tailings basins pollution potential [PDF]

, 2015
Tailings basins within mining areas may represent potential sources of environmental contamination for soil and underground water. In fact, the disposed muds are typically characterized by high concentration of heavy metals and other possibly dangerous

Improving the interpretation of undrained shear strength from piezocone penetration tests by integrating soil physical properties using a hybrid meta-heuristic algorithm

Journal of Rock Mechanics and Geotechnical Engineering
Conventional empirical equations for estimating undrained shear strength (su) from piezocone penetration test (CPTu) data, without incorporating soil physical properties, often lack the accuracy and robustness required for geotechnical site ...

Bearing capacity of floating geosynthetic encased columns (GEC) determined on the basis of CPTU penetration tests

Open Engineering, 2020
Floating geosynthetic encased columns (GEC) are an increasingly popular method of strengthening weak subsoil. Design of floating columns is a difficult and not fully recognized issue.

Numerical study of viscous effects during CPTu

7th International Conference on Geotechnical and Geophysical Site Characterization
Variable penetration rates during CPTu may impact cone readings through partial consolidation during penetration but also through viscous soil skeleton behaviour. The latter phenomenon is characteristic of dynamic penetrometers during fast penetration in fine-grained materials where tip resistance increases when the penetration rate increases.
