Hydraulic Property Estimation Using Piezocone Results

Journal of Geotechnical and Geoenvironmental Engineering, 2010
Governing underground water flow, hydraulic properties such as hydraulic conductivity or coefficient of consolidation are major geotechnical parameters. Determination of hydraulic properties, however, is traditionally time consuming and expensive. This research proposes an easy and economical way of determining the hydraulic properties of soils through

Consolidation After Undrained Piezocone Penetration. I: Prediction

Journal of Geotechnical Engineering, 1986
Piezocone measurements during steady cone penetration provide valuable soil-profiling and soil-identification data. The potential of the piezocone as a soil-exploration tool can be significantly enhanced if the pore-pressure decay that takes place after interrupting penetration can be interpreted to estimate the consolidation and/or permeability of the

Versatile site characterization by seismic piezocone

2005
Site investigations require the collection of geostratigraphic information about the soil layering and consistency, as well as a suite of soil properties and parameters for use in analytical and numerical calculations for design. The seismic piezocone test with dissipation phases (SCPTÙ) offers an optimal means to obtain up to five ...

Axial Shaft Response from Seismic Piezocone Tests

GeoSupport 2004, 2004
The axial-load-displacement-capacity response of drilled shaft foundations can be analyzed efficiently using the results of seismic piezocone tests (SCPTu) which provide four independent readings in the ground: cone tip stress, sleeve friction, penetration porewater pressure, and downhole shear wave velocity.

Estimating coefficient of consolidation from piezocone tests

Canadian Geotechnical Journal, 1992
Data have been reviewed from sites in Europe and North and South America as well as published data from South Africa. The review has concentrated on dissipation data from piezocone tests (CPTU) to compare predicted coefficient of consolidation and permeability values using published interpretation techniques with available reference values.

Miniature Piezocone for Use in Centrifuge Testing

Innovations and Applications in Geotechnical Site Characterization, 2000
A miniature piezocone was developed for use in centrifuge environments, including the piezocone design and fabrication. Several penetration tests were performed in centrifuge soil models encompassing normally consolidated and moderately overconsolidated clays, and medium dense to dense sands.

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.
