Abstract
A recent cavity expansion/critical state model for determining the in-situ OCRs from piezocone penetration tests (PCPT) is evaluated by preliminary calibration with data from several clays sites worldwide. The methodology relates OCR to the effective stress friction angle of the soil and normalized piezocone parameter, (qr-u)/σvo'. Distinction is made between Type 1 piezocones which measure the pentration pore water pressures at the cone tip/face and Type 2 piezocones with elements located behind the tip. The lean to plastic clays range from soft intact NC to hard fissured Oc deposits where both σp' and the effective stress friction angle are known. A further development combines the results from both types of piezocones so that the effective stress friction angle is not needed and OCRs are predicted solely from PCPT data
