It has also been found that well-graded gravelly soils, despite the much smaller void ratio than sand, can have an N-value and shear wave velocity as low as loose sand if it is loosely deposited. It has also been found that the formulae can readily estimate N-values with the factor ...

The standard penetration test (SPT) is a widely used in situ test method worldwide that can evaluate soil properties based on the blow counts (N-value). The N-value depends on soil properties, and the energy transferred to the drill pipe during hammering. Currently, European and American sch...
it is common that the second half of the MSD curve is noisy because of the low statistics for each MSD(n\(\Delta t\)) value. We decided to consider the first third of the curve
Most of these correlations do not have the intercept and thus can be written in Kc form, where Kc is the ratio of qc to N-value. Table 1 presents some of these correlations. Although they are well-cited in the literature, several of these correlations are based on N-values from ...
To meet an inspection requirement for a deck footing, I need to convert an SPT N value to lbs/sqft to calculate the numebr and area of footings I need on some marginal soils. Is there a simple formula to compute SPT N values to allowable load /sq ft for the footings? Replies continue...
Similar to the empirical formula for SPT N-value adopted previously by Cubrinovski and Ishihara (1999), the data of Swedish sounding tests were arranged and the empirical formula for the N_(sw)-value is proposed. This paper also addresses whether the void ratio range is a good parameter in...
