geotech.in_situ.spt.get_n_value

DataFrame.geotech.in_situ.spt.get_n_value(refusal=50, limit=False)

Return the N-value for each sample.

When a sample is a refusal, then the N-value is assumed as the value set in refusal. If limit is set to True, then any N-value exceeding refusal will be limited to refusal.

Warning

If limit is True while refusal is set to NA, nothing will get limited.

Requires:

blows_1

blows_2

blows_3

pen_1

pen_2

pen_3

Parameters:

refusal: int, default 50

Equivalent N-value for samples with total penetration less than 450 mm.

limit: bool, default False

If True, limits the resulting N-value to refusal.

Returns:

Series

n_value
