Definition

An in‑situ testing method that advances a cone‑shaped penetrometer into soil at a controlled rate while continuously recording tip resistance (qt), sleeve friction (fs) and, when equipped, pore pressure (u); these continuous measurements characterize stratigraphy and allow empirical or semi‑empirical estimation of soil type, relative density and strength parameters for geotechnical design and site
