A 4.5 m high retaining wall is supporting a horizontal backfill having
a unit weight of 15.7 kN/m³ and a saturated unit weight of 19.3 kN/m³.
Ground water table is located 3 m below the ground surface. Drained
friction angle for the backfill is 30°. Cohesion of soil = 20 kN/m²
a) Compute for the total force per unit length of wall for passive
condition.
b) Compute for the location of the resultant force.
