Non linear global dynamic analysis of reinforced slopes stability under seismic loading

Abstract

The aim of this work is to analyze the slopes stability under seismic loading in Lebanon using a global numerical dynamic approach. This approach allows taking into account important parameters that are generally ignored in simplified engineering methods as the soil deformability and frequency content of seismic input. Such parameters are critical in triggering instability under seismic loading. Analysis is conducted using elastoplastic soil behavior that could monitor the evolution of the slope state after an earthquake and clarify the most probable failure circles. It will focus on the slopes reinforcement in order to give recommendations for the most appropriate reinforcement scheme for vulnerable slopes under seismic loading.
