WebCBR = 292/DPI 1.12. log (DPI) = -1.05 + 2.03 * log (SPT) where CBR = California Bearing Ratio. DPI = DCP penetration index = penetration depth per blow. SPT = Standard Penetration Test. Now the penetration curve is made by placing DCP penetration (in mm) in Y-axis and no. of blows in X-axis.

WebThe Standard Penetration test (SPT) is a common in situ testing method used to determine the geotechnical engineering properties of subsurface soils. It is a simple and inexpensive test to estimate the relative density of soils and approximate shear strength parameters.
