CPT or Cone Penetration Test The Cone Penetration Test (CPT) is a geotechnical engineering method used to determine the soil properties and subsurface conditions at a specific location. It involves pushing a cone-shaped probe into the ground at a constant rate and measuring the resistance encountered as well as pore water pressure. CPT provides valuable data for soil classification, geotechnical design, and foundation assessments. Follow us at tunnel.engineering If you interested in tunnel engin
