Numerical analysis of geosynthetic-reinforced embankments on soft soils

Resumo

This paper analyzes, through numerical modeling in finite element software, the behavior of an
embankment reinforced with geosynthetics on soft soils. The results presented and discussed allowed us to
establish conclusions regarding the behavior of settlement, horizontal displacement, excess pore pressure, tension
and deformation in the geosynthetic as a function of time, depth and horizontal distance. In summary, the numerical
analyses presented satisfactory behavior and the results show that the insertion of geosynthetics does not influence
the response of some analyzed variables, except for the horizontal displacement. However, the use of geosynthetics
aims to increase the global stability of the soil mass through contact interactions and reduce embankment
deformation. The contributions of this work to the understanding of the behavior of geosynthetic reinforced
embankments on soft soils are highlighted.
