Cone penetration index for soil behaviour type prediction. [PDF]
Sci Rep, 2022 Several approaches have been proposed to classify soil types using both cone and piezocone penetration tests. The chart relating the normalized cone resistance (Q tn ) and the friction ratio (F r ) has proven to be the most reliable method.

Estimating Hydraulic Conductivity of Overconsolidated Soils Based on Piezocone Penetration Test (PCPT) [PDF]
Infrastructures, 2021 Overconsolidated (OC) soils may develop a low or negative pore pressure during PCPT. Thus, it is challenging to develop an “on-the-fly” estimation of hydraulic conductivity from PCPT results.
