An 8.5 m compacted fill is to be placed over the soil profile. Consolidation tests on samples from points A and B produced the following results.
a) Calculate the consolidation settlement caused by the weight of this fill. (Divide the top clay layer to 3 sub-layers and the bottom clay layer to 4 sub-layers as shown in the figure with appropriate height)
b) The combined settlement of the clay layers after 6 months
c) How long it takes for the top clay layer to reach 50% of consolidation?
