Relevant relations in order to better assess preconsolidation pressure values for the design of underground constructions in soft ground

摘要

Geotechnical design of underground constructions in soft ground needs a good knowledge ofrnthe variation of preconsolidation pressure variation with depth. Having very oftenly too rare values given byrnoedometer tests on good undisturbed samples, we will develop ways to cope with this lack of information, usingrndifferent layers physical properties and results of in situ tests like CPTu PMT and vane tests.
