On the influence of overconsolidation effect on the compressibility assessment of subsoli by means of CPTU and DMT

Abstract

The paper contains the analysis of the influence of overconsolidation effect on the values of constrained moduli, assumed by means of two most popular in situ advanced tests. The tested soils included two geological formations: normally consolidated tills of the Pomeranian phase and overconsolidated Tilos of the Posnanian phase. The overconsolidation ratio (OCR) was derived from CPTU, DMT and oedometric tests. The tests revealed that for the assessment of changes in constrained moduluj in the subsoil with CPTU and DMT, the formulas determining the relationship between cone resistance, DMT results and constrained moduli requires empirical coefficient different for soils of varied genesis.
