Settlement evaluation of reinforced embankment over a soft subgrade: numerical modelling with different soil models based on a full-scale study
Settlement evaluation of reinforced embankment over a soft subgrade: numerical modelling with different soil models based on a full-scale study
This paper presents results from comparative numerical analyses for an experimental study performed to investigate the soil behaviour for airfield pavement design in Bihać, Bosnia and Herzegovina. А 300 m long and 45 m wide multilayer reinforced embankment is constructed and surcharged in three zones by static loads over thick soft deposits. The monitoring comprises the observation of the settlements with a geodetic survey, horizontal inclinometers, and magnetic extensometers. Different constitutive models are used to model the terrain and estimate the settlements, and the results are compared to the monitoring. Although the results of the analyses generally confirm the terrain response, regardless of how precisely the terrain is modelled, it is difficult to accurately model all loading phases with constant values of the input parameters. The findings obtained through the numerical modelling are presented in the paper.
