• A piezocone data base is compiled from 36 well-documented clay sites with known stress histories. Only transducer readings on the cone tip or just behind the tip were considered. The normalized excess pore pressure to effective overburden ratio (Δu/σ_<vο>') indicated better trends with overconsolidation ratio (OCR) than the parameters (u/q_c) and B_q=Δu/(q_c-σ_<vο>). A direct relationship was also observed between the measured excess pore pressure (Δu) and effective preconsolidation pressure (σ_p'). Positive or negative values of pore pressure can apparently be measured behind the tip in heavily overconsolidated clays, while only positive values can occur at the tip. For the sake of consistency and simplicity of evaluation, this study suggests that standardization of piezocones place the porous element on the cone face. Alternatively, two transducers should be used.
