WebCubrinovski & Ishihara (2001) suggested an approach for estimating relative density from N-values accounting for gradation as characterized by the void ratio difference (e max-e min). A compilation of several correlations using energy and stress-corrected blow counts, (N 1) 60, is presented in Figure 2.10. Webblow count for 100mm penetration and SPT N is the blow count for 300mm penetration. The equiva-lence is therefore of n 100 and N 300. Data from anonymous loca-tions in …
