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
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.

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

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 ...
