Abstract:	Der Beitrag berichtet über eine neuartige Gründungsmethode für Schütt- und Dammkörper, wie beispielsweise Rohstoffhalden oder Verkehrsdämme, auf gering tragfähigen Böden großer Mächtigkeit. Zur Analyse des Trag- und Verformungsverhaltens dieser “selbstregulierenden interaktiven Membrangründung” wurden Zentrifugen-Modellversuche und umfangreiche numerische Berechnungen in Form von globalen Sensitivitätsanalysen und Parameterstudien durchgeführt. Deren Ergebnisse sowie der daraus abgeleitete Ansatz zur Dimensionierung werden im vorliegenden Beitrag vorgestellt. Eine Validierung des entwickelten Ansatzes erfolgt am Ende des Beitrags über eine Vergleichsrechnung mit dem numerischen Modell. On the load bearing behavior of the self-regulating interactive membrane foundation system The paper reports on a new foundation system, the self-regulating membrane foundation, for embankments on deep soft soil deposits, such as stockpiles or infrastructure embankments. The load bearing behavior of the system was analyzed by means of centrifuge model tests and comprehensive numerical simulations, such as global sensitivity analyses and parametric studies. The results of those analyses and the derived design approach are presented in the paper. The paper concludes with a validation of the design approach, by comparison with results of the numerical simulation.
