DCP to SPT N-value correlations
DCP to SPT N-value correlations
(OP)
Aside from a few graphs laying around the office here that appear to have been photocopied for the last 10 years... what is a reliable source for a DCP to SPT correlation?
idealy i'm looking for a graph of SPT N-value (blows per foot) VS DCP (blows per increment), with several lines plotted for various soil types.

i don't have any specific links handy to pass along. it might be wise to do some in-house correlations. try searching the forum since the subject has been discussed many times before.

Typically i wouldn't really need these charts as i'm familiarized with piedmont soils in my major region, however i have a project in coastal plains deposits near a beach with high water table.
tests were done in the top 4' only with a D-50 going below that, i'm being asked to combine them into a log showing the entire boring.
the charts i've seen in the office here are from the sower's paper or his other work, just pour quality and hard to read, as sowers was a teacher of a few at my office. the charts have a soil chart for coastal plains but i don't trust it.
I've found out what i needed, thanks for the help everyone.
