A Cone Penetration Test (CPT) is a method used to determine the geotechnical properties of soil. During the test, a cone-shaped instrument is pushed into the ground at a constant rate. The resistance encountered by the cone as it penetrates the soil is measured, providing valuable data about soil strength and stratification. CPT results help engineers and geologists assess soil conditions for construction projects, such as buildings and roads. The data collected can inform decisions on foundation design, excavation methods, and potential soil-related issues, ensuring safer and more efficient construction practices.
