Redo Problem 13.19, assuming that a surcharge pressure of 11 kN/m2 is applied on top of the backfill.
In Problem 13.19
a. Make the necessary calculation and draw the variation of Rankine's active pressure on the wall with depth.
b. Find the depth up to which tensile crack can occur.
c. Determine the total active force per unit length of the wall before the tensile crack occurs.
d. Determine the total active force per unit length of the wall after the tensile crack occurs. Also, find the location of the resultant.
