A concrete retaining wall 8 m high is supporting a horizontal backfill having a dry unit weight of 16.25kN/m3. The cohesionless soil has an angle of internal friction of 33 degrees and a void ratio 0f 0.65. (Use four decimal places) A. Compute the rankine active force on the wall. B. Compute the rankine active force on the wall if water logging occurs at a depth of 3.5 from the ground surface. C. Compute the location of the resultant active force from the bottom.
