For overconsolidated fine-grained soils, the precobsolidation pressure plays a critical role in settlement calculation. Are there new expressions for approximating its value without running a consolidation test.
Unfortunately, the pocket pressure meter will make no disnicrion between normally consolidated and overconsolidated soils. Also, the pocket pressure meter is meant to provide reading for the unconfined compressive strength of clayey soils and not its maximum past pressure. Thank you.
I agree with you, but the researcher in the paper I attached previously, tried to correlate the the experimental results of pocket pressure tests and consolidations test. there is no mathematical bases for that relation it is just best fitting curve between the the results of the two tests.
on other hand, it seems logic, in order to get significant penetration with the pressure meter, you have to exceed the per-consolidation pressure and get into normal consolidation state.
I checked this relation on some samples in my lab and the results is fair
I'm trying to model it with (FEM) and I hope I'll finished it soon
