3) A 5-m-high retaining wall is shown in Figure-2. Determine
A) Rankine active force per unit length of the wall and the location of the resultant
B) Rankine passive force per unit length of the wall and the location of the resultant
A 8-meter-high retaining wall, with a perpendicular back, retains the soil with a unit weight of 17.17 kN/m3. The cohesion and the internal friction angle of the backfill were measured as 13 kPa and 20°, respectively. Assume that there is no friction on the wall and the surface of the backfill is horizontal. Calculate the expected active force on the wall and the position of this force.
A 10-m retaining wall is shown in figure A, determine:
a. The active thrust on the wall due to soil and water
b. The active thrust on the wall due to soil only [dry]
c. The increase in force on the wall if the soil is fully saturated with rainwater.
