Numerische Simulation von Drucksondierungen mithilfe der Particle Finite Element Method

Abstract

AbstractIn‐situ‐Erkundungsmethoden wie die Drucksondierung werden als bewährte sowie kosten‐ und zeiteffiziente Verfahren zur Untergrundcharakterisierung eingesetzt. Die zur Interpretation herangezogenen Methoden werden laufend weiterentwickelt, um Einflussgrößen wie Teildrainage während der Versuchsdurchführung oder mikrostrukturelle Bindungen im Korngerüst berücksichtigen zu können. Diese beiden Effekte werden im vorliegenden Beitrag basierend auf der numerischen Simulation von Drucksondierungen mithilfe der Anwendung G‐PFEM, welche große Verformungen, Boden‐Struktur‐Interaktion und nichtlineares Materialverhalten berücksichtigt, untersucht. Die Ergebnisse verdeutlichen den Einfluss von Teildrainage und Mikrostruktur auf den gemessenen Spitzendruck und Porenwasserdruck, wobei unterschiedliche Tendenzen festgestellt wurden. Zudem konnte eine in situ durchgeführte Drucksondierung in postglazialen, feinkörnigen Sedimenten realistisch nachgebildet werden. Dies eröffnet einen möglichen Ansatz zur Kalibrierung nichtlinearer Materialmodelle, welche vielfach in der numerischen Analyse geotechnischer Randwertprobleme zum Einsatz kommen.
