WebThere have been a number of empirical correlations between cone tip resistance and SPT blowcount. The "qc/NM ratio has been believed to vary depending on soil type and test apparatus and procedure. It can be seen that the ratio of cone tip resistance to SPT blowcount decreases by the reduction of fine content or by increasing the mean grain size.
