A vertical retaining wall with smooth surface is 12 m high and retains granular soils. The surface of the supported soil slopes upwards from the top of the wall at an angle of 20°. The angle of internal friction of soil is 32°. (Assume y = 20kN/m³). Assume the wall can move away and towards granular soil. The groundwater table is well below the base of the retaining wall. a): Compute Rankine state of total active thrust acting parallel to the slope (in kN/m). Answer: b): Compute Rankine state of total passive thrust acting parallel to the slope (in kN/m). Answer:

A vertical retaining wall with smooth surface is 12 m high and retains granular soils. The surface of the supported soil slopes
upwards from the top of the wall at an angle of 20°. The angle of internal friction of soil is 32°. (Assume y = 20kN/m³). Assume the
wall can move away and towards granular soil. The groundwater table is well below the base of the retaining wall.
a): Compute Rankine state of total active thrust acting parallel to the slope (in kN/m).
Answer:
b): Compute Rankine state of total passive thrust acting parallel to the slope (in kN/m).
