Numerical Study of the Effect of Clay Structure on Piezocone Penetration Test Results
International Journal of Geosynthetics and Ground Engineering, 2021Studies of the effect of clay structure on piezocone penetration test (CPTU) results are beneficial for interpreting CPTU data in naturally or artificially cemented structured clays. The structured Cam clay (SCC) model was implemented into Abaqus, and the validity of the user-defined material (UMAT) subroutine of SCC was verified by predicting the ...

A Penetration Processing Study of Piezocone Penetration Test in Cutoff Wall
2018The penetration processing of piezocone penetration test (CPTU) is very important for the analysis of stress-strain of soil bentonite cutoff wall (SBCW) in landfill site. In this paper, CPTU is conducted in the soil bentonite cutoff wall, which is located in Jiangsu province, China.

Assessment of Measurement Errors of Piezocone Penetration Test in Soft Clay
Geotechnical Testing Journal, 2016Uncertainty evolved through in situ testing, such as measurement error, is a major concern in the characterization of soft clays that suffer from the low strength and high sensitivity of soil properties. In this research, 20 piezocone penetration tests (CPTUs) in a laboratory calibration chamber and 25 CPTUs performed in marine soft clay in Lianyungang,

Finite-Element Analysis of Inclined Piezocone Penetration Test in Clays
International Journal of Geomechanics, 2005A three-dimensional finite-element analysis was performed to analyze the effect of soil anisotropy on the inclined piezocone penetration test in normally consolidated clay. The piezocone penetration was numerically simulated based on a large strain formulation using the commercial finite-element code ABAQUS, and the anisotropic modified cam clay model (

Symposium on the Application of Geophysics to Engineering and Environmental Problems 1999, 1999
Soil densification by vibro-replacement is commonly prescribed to reduce the potential for large strains and instability associated with pore pressure generation in granular soil during earthquakes. Penetration tests such as the standard penetration test (SPT) and piezocone penetration test (CPTU) are used to assess the need for such ground treatment ...

Effective friction angle of clays and silts from piezocone penetration tests
Canadian Geotechnical Journal, 2018An existing effective stress limit plasticity solution for piezocone penetration tests (CPTu) is calibrated to evaluate the effective stress friction angle ([Formula: see text]) for undrained conditions for a variety of fine-grained soils ranging from natural lean to plastic clays and clayey silts from marine, alluvial, lacustrine, deltaic, and ...
