Development and validation of a method to predict the soil thermal conductivity using thermal piezocone penetration testing (T-CPTU)

Canadian Geotechnical Journal, 2022
A new in situ thermal piezocone penetration test (T-CPTU) system is developed to determine the thermal properties of soil. It is expected to overcome most of the shortcomings observed in existing in situ test techniques. Based on Fourier's heat conduction equation and pore pressure dissipation theoretical equation, a method for calculating the thermal

Marine soil behaviour classification using piezocone penetration test (CPTu) and borehole records

Canadian Geotechnical Journal, 2021
Several piezocone penetration test (CPTu)-based soil behaviour classification systems (SBCs) have been developed for standard sites, where clays, silt, and sand dominate. However, problems can occur when applying the SBCs to offshore sites, where the marine soils may be decomposed from rocks or mixed with artificial fills.

Empirical correlations of soil parameters based on piezocone penetration tests (CPTU) for Hong Kong-Zhuhai-Macau Bridge (HZMB) project

Transportation Geotechnics, 2021
Abstract The site investigation is a key part of the foundation analysis and design in the Hong Kong-Zhuhai-Macao Bridge (HZMB) mega project, as it provides accurate geotechnical parameters. This paper discusses about the collection of undisturbed soil samples, laboratory tests, and extensive piezocone penetration tests (CPTU) performed at the Pearl ...

Cavity expansion-based interpretation of piezocone penetration test (CPTu) data in clays

Géotechnique
A cavity expansion-based method is proposed in this paper to correlate the relevant findings with the piezocone penetration test (CPTu) data in clays. The rigorous and explicit solution for both spherical and cylindrical undrained cavity expansion is adopted based on a unified critical state constitutive model for clays and sands.

Estimation of Undrained Shear Strength of Overconsolidated Clay Using a Maximum Excess Pore Pressure Method Based on Piezocone Penetration Test (CPTU)

Geotechnical Testing Journal, 2020
ABSTRACT Many methods can be used to evaluate the undrained shear strength (su) in unconsolidated or normally consolidated clay. However, among the many methods, few methods can be used to evaluate the su value in overconsolidated clay. In this paper, based on the piezocone penetration test (CPTU), the maximum excess pore pressure method

An Optimized Artificial Neural Network Structure to Predict Clay Sensitivity in a High Landslide Prone Area Using Piezocone Penetration Test (CPTu) Data: A Case Study in Southwest of Sweden

Geotechnical and Geological Engineering, 2016
Application of artificial neural networks (ANN) in various aspects of geotechnical engineering problems such as site characterization due to have difficulty to solve or interrupt through conventional approaches has demonstrated some degree of success. In the current paper a developed and optimized five layer feed-forward back-propagation neural network
