Calculation and Forecast of Settlement of widened embankment

Résumé

The 2-D FEM has been employed to analyze the settlement of widened embankment and the interactional behavior of new and old embankments. In the calculation the elastic-plastic constitutive model (Drucker-Prager model) and constitutive model of interface with no thickness have been applied to consider the plasticity of soils and the nonlinear behavior of Interface element. This text gives the result of settlement according to the modeling method. The comparison between the predicted and measured values proves that the constitution and the models are reliable.
