Refer to Problem 7.3.

a. Draw the Rankine passive pressure distribution diagram behind the wall.

b. Estimate the Rankine passive force per foot length of the wall and also the location of the resultant.

Problem 7.3

Refer to Figure 7.6a. Given the height of the retaining wall, H is 21 ft; the backfill is a saturated clay with φ = 08, c = 630 lb/ft² γ_sat = 113 lb>ft³

a. Determine the Rankine active pressure distribution diagram behind the wall.

b. Determine the depth of the tensile crack, z_c.

c. Estimate the Rankine active force per foot length of the wall before and after the occurrence of the tensile crack.
