Standard Penetration Testing (SPT)

Standard Penetration Testing (SPT) na fundamental in-situ soil investigation method wey dey widely use in geotechnical engineering to assess ground condition, soil property, and bearing capacity at foundation site. Dis essential procedure involve drive standardized split-barrel sampler into ground using controlled blow from falling hammer, measure number of blow wey require to advance sampler fixed distance. Resulting N-value provide critical data about soil density, strength, and composition, make SPT indispensable for deep foundation design, piling project, and ground improvement planning. Foundation engineer dey rely on SPT result to determine appropriate pile type, depth, and load-bearing capacity when develop foundation strategy for building, bridge, and infrastructure project.
