Effective Modulus (E') for Cohesionless Soils from SPT
Estimates E' for cohesionless soils using selectable Kulhawy and Mayne (1990) and Bowles (1996) SPT correlations.
Soil Profile Plot
Select a cohesionless-soil SPT correlation, then enter depth and corrected SPT N values by sample. E' is computed with the selected equation and plotted against depth.
