building of width 12 m and length 300 m (parallel to the retaining wall) will impose a surface stress of 150
kPa. In the preliminary design, the long edge of the building is located 1 m from the wall. Assume the
building load can be treated as a strip load
(a) Plot the distribution of the lateral force increase with depth up to a depth of 4 m.
(b) What is the maximum value of the lateral force increase, and where does it occur?
(c) If the embedment depth of the retaining wall is 4 m, calculate the maximum additional moment about
the base of the wall (point Oin Fig 25) from constructing the building.
(d) What advice would you give to the developer regarding how far the apartment should be located from
