JOHANNES, Briceño, et al. Evaluation of Stability in Embankments through the Consolidation Process Using Numerical Models. Rev Politéc. (Quito) [online]. 2025, vol.56, n.2, pp.49-56. ISSN 2477-8990.  https://doi.org/10.33333/rp.vol56n2.05.

In the road construction process, cross sections are generated as a result of the modification of the original topography. These will respond to the geometric design of the road and will be built with earth movement either in cut or in filling. The embankment cross section is built with filling material compacted in layers and with smoothed slopes to guarantee its stability. In rainy regions where the material is in a saturated condition for many months of the year, and depending on the type of material, the embankment may suffer deformations that affect the stability of the section and its operability. In the design of these cross sections, these conditions are rarely taken into consideration, nor is the effect on road structure safety and user comfort evaluated. This research proposed subjecting an embankment cross section to different drainage conditions and seismic forces to evaluate how settlement due to consolidation and stability varies. The Finite Element numerical method was used as an alternative to the Terzaghi Onedimensional Consolidation Theory. The results showed that material saturation and seismic action affect stability and increase settlements considerably. Therefore, when designing the cross sections of a road, these conditions, the effects they produce, and the consequences on the durability of the work, safety, and user comfort must be considered.
