Numerical analysis of an unreinforced embankment on soft soil

Resumo

The present work analyzed, through numerical modeling, the behavior of an unreinforced embankment
on soft soil. The simulations were performed in the Abaqus software, from which the Mohr-Coulomb failure
criterion was established for the granular material of the embankment and the Modified Cam Clay model for soft
soils. As result, the paper presents and discusses the behavior of settlement, horizontal displacement, excess pore
pressure, and effective stress variation as a function of time, horizontal distance, and depth. The adopted numerical
model and the observed behavior patterns are satisfactory so that the results of this study can assist in the analysis
of the performance of embankments on soft soils.
