Prediction of Angle of Internal Friction Based on SPT N Values
igs.org.inStandard penetration test (SPT) is widely used in-situ test for measuring the geotech-nical properties of soil, bearing capacity of soil and shear strength of soil. For the construction site, standard penetration test is required to get the undisturbed soil sam-ple. The penetration resistance depends on grain size of soil.

As indicated in Eq. 2.5, is approximately equal to where is the vertical effective stress, in kPa. Suggested maximum values of CN range from 1.7 to 2.0 (Youd and Idrixs, 1997, 2001).
