Numerical simulation of critical state model (p,q,θ) in embankments on soft soils

Abstract

In order to its utilisation in the numerical simulation of constitutive behaviour of soils, critical state model (p,q,0) is described. Using this formulation, the results of application of a numerical method based on finite element method in an embankment on soft soils (reinforced or not) are also presented and analysed. Toe effect of the variation of the over consolidation ratio and coefficient of earth pressure at rest of the foundation, on the embankment behaviour, is analysed too.
