Abstract:

Knowledge of seismic passive earth pressure is very much important to design the retaining wall in the earthquake prone region. Using pseudo-dynamic approach, a limited number of investigations have been performed to obtain the seismic passive earth pressures considering a constant magnitude of shear modulus throughout the backfill. Truly speaking, the shear modulus and thus shear and primary wave velocities in the soil medium vary with the depth. However, no significant attention has been provided by the researchers towards the determination of seismic passive earth pressure behind a non vertical cantilever retaining wall with varying shear modulus throughout the backfill. Using pseudo-dynamic approach,
this paper presents a study on the seismic passive earth pressure behind a nonvertical rigid cantilever retaining wall by considering time and phase difference of acceleration in the backfill; and the variation of shear modulus with depth. The results are provided in tabular and graphical form.
