Auf dem 21.000 m<sup>2</sup> großen Baufeld an den Elbbrücken, unmittelbar neben dem S-Bahnhof, wurden bis Februar 2023 unter anspruchsvollen zeitlichen und technischen Rahmenbedingungen die Spezialtiefbauarbeiten durchgeführt. Zur Gründung des Hochhauses kamen 63 Großbohrpfähle mit einer beeindruckenden Tiefe von jeweils 83 Metern zum Einsatz. Darüber hinaus waren umfangreiche Sicherungsmaßnahmen für die Baugrube sowie komplexe Gründungen im Sockelbereich und für angrenzende Nebenbauwerke erforderlich. Die Baustelleneinrichtung musste dabei den parallelen Einsatz mehrerer Gewerke und Großgeräte ermöglichen – eine logistische Herausforderung, die das Baustellenteam kontinuierlich forderte.

Selecting the right one is crucial for accurate results and high-quality predictions. Therefore, understanding the interactions between the material model's mathematical structure, input parameters, and the modelling process is essential. This paper investigates the impact and sensitivity of input parameters for the linear-elastic, ideal plastic Mohr-Coulomb Model, the elasto-plastic Hardening Soil Model, and the Soft Soil Model, focusing on tunnel cross-section deformations in challenging soft soils.Using the Finite Element Method Plaxis2D, a model accounting for relevant tunnelling boundary conditions is created. The three material models are calibrated based on simulated oedometric and triaxial tests to ensure comparable soil behaviour. The results demonstrate that the cross-sectional deformations determined from the two non-linear material models exhibit minimal discrepancy. For both, the heave of the invert, a consequence of tunnel excavation-induced unloading, represents the most significant deformation. The linear one proves to be inappropriate for modelling the given context due to an unrealistically large heave. The subsequent sensitivity analysis highlights the relevance of the soil unit weight γ, the stiffness <span></span><math></math> in the HSM and the swelling coefficient κ* and the Poisson's ratio ν<sub><i>ur</i></sub> in the SSM.</p>","PeriodicalId":43155,"journal":{"name":"Geotechnik","volume":"48 3","pages":"203-212"},"PeriodicalIF":0.4,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145181675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
