Abstract (EN): In this work the two-dimensional finite difference program Fast Lagrangian Analysis of Continua (FLAC) was used to model the seismic response of a geosynthetic reinforced steep slope. The reinforced slope, with face inclined of 80º, is 6.0 m high and reinforced with 10 horizontal reinforcement layers of 4.8 m long. The paper presents a numerical study that was carried out to analyze the influence of the input motion and boundary conditions. The permanent displacements of the slope face and reinforcement tensile forces are analyzed and compared. The introduction of absorbing boundaries is essential to avoid the reflection of outward propagating waves back into the model. A single frequency harmonic motion may be useful to carry out parametric analyses, however the magnitude of the seismic response may be excessive or diminished.
