TIME AND FREQUENCY DOMAIN MODELS FOR THE SEISMIC ANALYSIS OF GEOGRID REINFORCED SOIL WALLS

This paper proposes a mathematical model for the dynamic behavior of geogrid reinforced soil retaining structures under bedrock horizontal excitation. A linear model of the soil without reinforcements (time and frequency domain) is firstly introduced, then a Newtonian non-linear model for the dynamics of soils with geosynthetic interlayer reinforcements is presented. The proposed theory has been checked with numerical simulation of case histories: a reduced scale model of a retaining wall and a full scale railway track retaining wall observed under a record of the Kobe earthquake.
