Hi All,
Is there any way to tell if the soil is over-consolidated or normally consolidated just based on Atterberg results, moisture contents, SPT N-values and pocket penetrometer?
Thanks for your answers,

RE: normally consolidated or over-consolidated

other than sensitive marine clays, if the water content is at the liquid limit, that's typically reflective of normal consolidation.

in marine clays, it can be a bit different. If a pocket penetrometer shows undrained shear strength different than some Su/P' ratio, it could have some stress history? Certainly can't go by blow counts in sensitive marine clays!

RE: normally consolidated or over-consolidated

Hey Silty look up the following it is a good resource for correlating any field or lab test to soil properties. Its a bit dated but you can track down more recent correlations by reviewing the citations and who's been citing them.

Manual on Estimating Soil Properties for Foundation Design

RE: normally consolidated or over-consolidated

Be careful with oven dried moisture content. If soft clay is likely to be encountered, go CPTu/DMT. SPT and pocket penetrometer are crude for soft clay/silt.
