The issue of settlement and the calculation of the thickness of the deformation zone are addressed in this paper. A short overview is given concerning the thickness of the deformation zone values used in general practice; the available soil models are also briefly introduced. A particular problem is used to compare the results of obtained depth of the influence zone calculated by available formulae and estimated by finite element analyses with different soil models, such as the “hardening soil”, the “Cam-Clay” and the “hardening soil with small strain” models. The deformation zone of a soft clay layer beneath a 10 m-high and 80 m-wide embankment is evaluated, and the results are compared. Special attention is given to the soil models and their capabilities and drawbacks for calculation of deformations due to large embankments.
