This article presents the results of in‐situ and triaxial testing of tertiary soils (Pannonian sand and Oligocene clay) performed for two major Hungarian projects. The shear strength of these formations varies greatly. Just interpreting the shear strength of tertiary soils poses a number of questions, which definitely exceeds the scope of existing standards. Since extracting multiple samples from the overconsolidated, high‐density samples was not possible, the necessary parameters had to be determined from one larger specimen. Through short examples, it is demonstrated how the test results can be described using soil models and transferred into geotechnical design, highlighting the limits of numerical modelling (in case of these soils).
