WebJul 13, 2024 · Researchers from various countries have proposed empirical correlations between soil V s values and N-SPT [19,20,21,22]. According to SPT implementation standards, N-SPT is the number of blows required to obtain the last 30 cm of sample tube penetration from a total of 45 cm at each test step.
