Interpretation of cone penetration test data for underconsolidated clay
In this study, cone penetration test data is correlated to vane shear and triaxial undrained shear strength test data for a saturated and underconsolidated marine clay. It is shown that cone penetration test data not corrected for pore pressures underestimates undrained shear strength. …

Influence of penetration force in clay soils due to speed rate effect
This research discusses the effects of penetration rate on the penetration resistance in clayey soils for five different speeds of penetrations. In order to install the pile through hydraulic system, it is crucial to understand the required penetration force needed to do the job. Generally, the …

Review of CPT based design methods for estimating axial capacity of driven piles in siliceous sand
The Cone Penetration Test has been used for more than 30 years for soil exploration purposes. Its similarities in mode of installation with driven piles provides the potential of linking key variables of pile design and performance, such as base resistance and shaft friction, to measured cone tip …

Improving CPT-Based Earthquake Liquefaction Hazard Assessment at Challenging Soil Sites
… is correlated with metrics computed from in-situ tests like the Cone Penetration Test (CPT). While CPT-based procedures have been shown to accurately predict liquefaction occurrence in homogenous, sandy soil profiles, they tend to over-predict the occurrence of liquefaction in challenging, highly …
