The Standard Penetration Test (SPT) is a widely used method for assessing the geotechnical properties of soil. During the test, a hollow sampler is driven into the ground at a specific depth using a hammer. The number of blows required to penetrate the soil a certain distance is recorded, providing valuable information about soil density and strength. SPT results help engineers and geologists understand soil behavior, which is crucial for designing foundations and other structures. The data obtained can influence construction decisions and ensure safety in projects involving various types of soil, including clay, sand, and gravel.
