Question

Calculate the static active earth pressure and seismic-induced earth pressure increase for a concrete retaining wall with the back-wall angle β of 10^o with the following given conditions:

1. Wall height: 8 m.
2. Backfill density: 1.8 g/cm³.
3. Backfill angle of internal friction: 36^o.
4. Concrete wall back and backfill interface friction angle δ: 22^o.
5. The wall is located at a seismic zone with design seismic coefficients: k_v=0.12 (vertical direction) and k_h= 0.36 (horizontal direction).
6. The soil below wall base is strong enough to fulfill bearing capacity requirement.
