SPT AND RELATIVE DENSITY IN COURSE SAND

The discussers view the Standard Penetration Test (SPT) as only an approximate and even crude indicator of the relative density of in-site foundations, but a practical substitute for costly high order, field and laboratory density tests. Comparison of estimated (from a graphical chart based on the discussers initial research) and the authors' measured values of relative density are tabulated. These comparisons show that in each case an intrerpretation from the chart could indicate denseness that is reasonably close to that of the measured relative densities obtained in the authors' studies. Comments are also made on some investigators concern that the correlations of SPT values and in-situ relative density have not been reasonable for sands in the very dense range, in excess of 90% relative density.
