Pseudo-dynamic approach of seismic earth pressure behind cantilever retaining wall with inclined backfill surface
Debabrata Giri

    Knowledge of seismic earth pressure against rigid retaining wall is very important. Mononobe-Okabe method is commonly used, which considers pseudo-static approach. In this paper, the pseudodynamic method is used to compute the distribution of seismic earth pressure on a rigid cantilever retaining wall supporting dry cohesionless backfill. Planar rupture surface is considered in the analysis. Effect of various parameters like wall friction angle, soil friction angle, shear wave velocity, primary wave velocity, horizontal and vertical seismic accelerations on seismic earth pressure have been studied. Results are presented in terms of tabular and graphical non-dimensional form.
Key Words
    seismic earth pressure; retaining wall; Mononobe-Okabe method; pseudo-static approach; pseudo-dynamic method; seismic acceleration.
