A compacted fill of 3.0 m height is to be placed over a large area. The soil profile under the area is shown in the scheme below. An oedometer test on a sample from point A produced the following results: Ce C, eo o(kPa) Sample A: 0.40 0.08 1.10 70.0 These results can be used in settlement calculations for the soft clay stratum as a whole. Compute the total settlement below centre of the area due to the weight of the fill.
