A large embankment is to be built on the 5 m thick layer of normally consolidated clay that is overlain by a 2-m thick layer of sandy soil in the manner shown in Figure E4-1. The groundwater table is located at the sand-clay interface, and capillary rise in the sandy soil is negligible. The unit weight of the sandy soil is 18.5 kN/m³. The clay has a specific gravity of solids (Gs) equal to 2.68 and a moisture content (w) of 50.2%. The results from a one-dimensional (oedometer) consolidation test on a sample of the same clay from the middle of the layer gave an average value of 0.245 for the compression index (Cc). If the final (ultimate) effective stress at the middle of the layer after the application of the embankment loading is 120 kN/m², what is the average ultimate primary consolidation settlement of the clay layer resulting from this loading? applied embankment load Sandy soil 2 m 5 m Clay layer Impermeable layer

Question
A large embankment is to be built on the 5 m thick layer of normally consolidated clay that is overlain by a 2-m thick layer of sandy soil in the manner shown in Figure E4-1. The groundwater table is located at the sand-clay interface, and capillary rise in the sandy soil is negligible. The unit weight of the sandy soil is 18.5 kN/m3. The clay has a specific gravity of solids (Gs) equal to 2.68 and a moisture content (w) of 50.2%. The results from a one-dimensional (oedometer) consolidation test on a sample of the same clay from the middle of the layer gave an average value of 0.245 for the compression index (Cc). If the final (ultimate) effective stress at the middle of the layer after the application of the embankment loading is 120 kN/m2, what is the average ultimate primary consolidation settlement of the clay layer resulting from this loading?
