Poprawny opis podłoża jest niezbędny do optymalnego zaprojektowania posadowienia oraz ma praktyczny wymiar ekonomiczny dla wielu problemów projektowania geotechnicznego. Ocena wytrzymałości gruntu wymaga doboru odpowiednich, zestadaryzowanych badań oraz zwalidowanych metod interpretacji, w oparciu o doświadczenia lokalne. Niemniej poprawność wnioskowania w zakresie rozwiązań posadowienia wymaga wypracowania charakterystyki parametrów podłoża budowlanego w podziale na jednostki o zasięgu regionalnym.Wartykule porównano wyniki wytrzymałości na ścinanie gruntów zróżnicowanych lito-genetycznie (między innymi organicznych i makroporowych, pylastych – lessy) uzyskane w trakcie badań laboratoryjnych i terenowych na poletkach badawczych z obszaru Polski. Wybrane podłoża reprezentują osady o różnej litologii, genezie i stopniu przekonsolidowania. Badania obejmowały zarówno badania in situ (sondowania FVT, CPTU i DMT) jak i walidujące badania laboratoryjne. Uzyskane wyniki pozwoliły na zweryfikowanie znanych z literatury współczynników korelacyjnych i wzorów dla określenia parametru cu/Su uzyskiwanego różnymi metodami w ujęciu regionalnym, jako podstawa do wyznaczania wiarygodnych do projektowania parametrów geotechnicznych.Bibliografia
