| Abstract | Today, analysis of the stability and study of the behaviors of retaining walls and soil slopes are important topics in soil mechanics/geotechnical engineering. Soil improvements, especially performance must give attention to behaviors particularly for reinforced earth slopes is their performance against earthquakes. In this study, we attempt to perform numerical modeling studies using FLAC3D finite difference software. With the FISH programming language available in this software as well as the existing attenuation models, some arbitrary behavior and precise modeling are done. The main purpose of this study is to investigate the dynamic and nonlinear behavior of reinforced earth slope. For this purpose, an instrumented articulated roof attic that has been constructed and operated as a road embankment is used as the base model. Seismic conditions are applied to the model using the acceleration mapping of several major earthquakes of Iran and the world. The soil behavioral model has been based on a soft or hardened Mohr-Coulomb model with the capability to incorporate nonlinear behavior in static analysis with nonlinear attenuation models in dynamic analysis. |
