Piezocone Penetration Testing in Soft Cohesive Soils

1985
The difficulty in obtaining samples for laboratory testing in very soft cohesive marine deposits necessitates the use of in-situ testing methods. Piezocone penetrometers that measure the tip resistance qc, sleeve friction fs, and the generated pore pressure u, are one of the most repeatible and reliable in-situ testing methods.

An analytical study of the effect of penetration rate on piezocone tests in clay

International Journal for Numerical and Analytical Methods in Geomechanics, 2006
Finite element cavity expansion analysis investigating the effect of penetration rate on piezocone tests in clay is presented. A coupled analysis was performed, in which the rate of cavity expansion was linked to the penetration rate of the cone and the cone angle, using the assumption that the deformation was wholly radial, and took place only between

Multifunctional Piezocone Penetration Testing in Geotechnical Practice

Applied Mechanics and Materials, 2011
Cone penetration test is a fast and efficient in-situ test technique. With the development of sensor technology and the use of new probes, such test is employed in more fields and reveals more soil parameters. Based on advanced CPTU equipment, soil types were classified.

Piezocone Penetration Testing in Atlantic Piedmont Residuum

Journal of Geotechnical and Geoenvironmental Engineering, 2001
Piezocone soundings were performed in residual silts and fine sands of the U.S. Atlantic Piedmont geologic province to investigate penetration pore-water pressures and subsequent dissipation characteristics in these nontextbook geomaterials. Piedmont residuum has been formed by the in-place weathering of Paleozoic schist, gneiss, and granite.

A Soil Stratifying Method Based on Piezocone Penetration Test

Applied Mechanics and Materials, 2013
This paper introduces the empirical method of classifying soil layers with CPTU. Pore pressure dissipation test was taken in a certain soft clay field, according to the characteristics of penetration curve and the value of static point resistance, frictional resistance, friction-resistance ratio, soil horizon was divided.

Determination of Hydraulic Conductivity Using Piezocone Penetration Test

International Journal of Geomechanics, 2003
An elastoplastic, finite-strain, coupled theory of mixtures in an updated Lagrangian reference frame is applied to the piezocone penetration test to estimate the hydraulic conductivity of the soil ...
