Abstract:	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). In diesem Artikel werden die Ergebnisse von In-situ- und Triaxialversuchen von Tertiärböden (Pannonischer Sand und Oligozäner Ton) für zwei große ungarische Projekte vorgestellt. Die Scherfestigkeit dieser Formationen variiert stark. Die Interpretation der Scherfestigkeit von Tertiärböden wirft eine Reihe von Fragen auf, die den Rahmen der bestehenden Normen eindeutig übersteigen. Da es nicht möglich war, mehrere Probestücke aus den überkonsolidierten, sehr dichten Proben zu gewinnen, mussten die notwendigen Parameter aus einer größeren Probe bestimmt werden. Anhand von Beispielen wird gezeigt, wie die Testergebnisse mithilfe von Bodenmodellen beschrieben und in das geotechnische Design übertragen werden können, wobei die Grenzen der numerischen Modellierung (bei diesen Böden) hervorgehoben werden.
