A parametric case study of a 25,5 m deep excavation is presented. Finite Element analysis was performed using Modified Mohr-Coulomb and Hypoplastic Clay constitutive soil models. The results of the FE analysis were compared to in-situ displacements measurements taken during construction as well as to the results of calculations made using dependent pressures method. Final conclusions concerning the applicability of the Hypoplastic Clay constitutive soil model for modelling of deep excavations made in soft clay in terms of accurate determination of horizontal displacements of the excavation wall are presented.
