CPT Correlation with Soil Density

CPT Correlation with Soil Density

CPT Correlation with Soil Density

(OP)
In order to estimate silty sand, clayey silt soil density, could anybody advises a correlation factor, please.   

RE: CPT Correlation with Soil Density

You can find a relationship with relative density, see

NCHRP SYNTHESIS 368 freely downloadable,

http://onlinepubs.trb.org/onlinepubs/nchrp/nchrp_syn_368.pdf

Correlations may also be found in

Handbook of Geotechnical Investigation and Design Tables
Burt Look
Taylor and Francis, 2007

Hope this helps






 

RE: CPT Correlation with Soil Density

and how accurate are these if the specific gravities of the materials are significantly greater or lower than, say 2.65?

RE: CPT Correlation with Soil Density

Too big a question for me, BigH; just trying to help. Certainly operating just on standard correlations is not the best way to know a particular soil.
