An Analytical Study on Penetration and Pore Pressure Dissipation of Piezocone Test in Typical Normally and Over-Consolidated Silty Clays

The degree of the over-consolidation ratio (OCR) silty clay affects soil’s mechanical properties and in situ test results. present study utilized numerical analysis to investigate behavior cone penetration pore pressure dissipation typical soils, while also taking into account impact (OCR). Effective stress finite-element analyses, which accounted for considerable deformation, were carried out at various OCRs. model assumed soil as a homogeneous material obeying modified Cam Clay (MCC) model. significant advance this work is evaluation effect OCR on resistance data calculation formula ch clay. An inversion method based results piezocone tests was proposed terms strength clay, great importance parameters Yellow River Delta region. This paper presents consolidation coefficient normally over-consolidated clays corrected disadvantage that traditional conversion methods could not take effects account.
