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.
