Resumo:
The main objective of this research is to investigate the seismic response of a soil slope reinforced with geosynthetics, located in an active seismic region of Peru. The 10.40m high slope was reinforced with 9 horizontal layers of geosynthetics 10m long. The aspects studied in this work are related to the slope static stability, the dynamic response of the embankment under seismic excitation, the effects of the boundary conditions and the different types of mechanical damping, the influence of the friction angle of the soil that forms the embankment. The seismic analysis was carried out with the computational program FLAC, where the reinforcement layers were represented by means of cable elements. The soil mechanical behavior was simulated through the Mohr- Coulomb elastoplastic constitutive model, considering both the frequencydependent Rayleigh damping and the hysteretic damping (dependent on the soil shear deformation) with the objective to understand the influence of all these variables on the dynamic response of the structure and on the distribution of traction forces along the reinforcements. A good knowledge about the mechanical behavior of soil reinforced structures is essential for an efficient engineering design, under the technical and economical points of view, mainly in the Andean countries of South America.
