Three-dimensional numerical simulation of the dynamic behavior of slopes of the Costa Verde cliff - Armendariz Sector

Resumo

In this research, slope stability was evaluated in dynamic terms, specifically in the Armendariz descent,
by means of three-dimensional numerical analysis using the finite element technique and finite differences, where
the parameters were calibrated for static and dynamic conditions by means of large-scale tests and wave
propagation, respectively. For the estimation of the parameters under static conditions, the elastic-plastic response
trajectory of the large-scale direct shear test was taken into account and compared with the numerical model with
the same test characteristics until the soil parameters were found by curve fitting (comparison with the response
of the in-situ test). For the estimation of the parameters under dynamic conditions, comparisons were made
between the dynamic responses, in terms of accelerations, recorded instrumentally with the three-dimensional
dynamic wave propagation analysis, considering the soil stratigraphy and the geometric configuration of the
slopes.
