Deformation parameters of soils determined by the cone penetration test

The article deals with the derivation of correlation relations from the cone penetration test, which are applied as input parameters in the calculations of advanced constitutive soil models. Numerical modelling has become important part of geotechnical calculation. Hand in hand there is a big demand for accurately determined input parameters for constitutional models, that are not usually determined by IG surveys. On the model area we applied fieldworks as cone penetration tests and boreholes to obtain detailed parameters. Soil samples were examined in laboratory to create own database of values. Derived correlations include compression index C-c and recompression index C-r.
