(b) A rectangular raft foundation of a building with two axes of symmetry is composed of two areas as shown in Figure Q1.1. Area 1 is to carry a uniformly distributed load of 60kPa, while Area 2 is to carry a load of 240kPa. A site investigation indicates that the soil is alluvial clay with a one-dimensional modulus given as E = (6 + 2z)MPa where z is the depth below the ground surface in m. Use Fadum's chart (see Figure Q1.2) to estimate the ultimate settlement at the middle of shorter side (point A) of Area 1. 28m 10m 240kPa A 20m 6m 2 10m 1 4m 60kPa 8m 6m 14m Figure Q1.1 A rectangular raft foundation: Geometry of the foundation together with plan view of the uniform loads transmitted to the soil.
