normally consolidated or over-consolidated

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!

Thanks fattdad

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.

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.

White Paper - Guide to Integrate Large-Format Additive
As with any new technology, getting into large-format 3D printing begins with investigation. The first question may be a simple one: what does “large-format” mean? For 3D printers, “large” is a relative term. Many extrusion-based (FFF) 3D printers are referred to as desktop machines, because they fit on table space. Some of these have very respectable build volumes – but when it comes to “large-format,” the machines will need their own dedicated floor space. Large-format 3D printers have significant build volumes and are most often found in professional settings, like manufacturing facilities and R&D centers. Download Now
eBook - Efficient and Effective Production Support with 3D Printed Jigs and Fixtures
Jigs and fixtures offer manufacturers a reliable process for delivering accurate, high-quality outcomes, whether for a specific part or feature, or for consistency across multiples of parts. Although the methodologies and materials for producing jigs and fixtures have evolved beyond the conventional metal tooling of years past, their position as a manufacturing staple remains constant due to the benefits they offer.
