Question 4 (20 marks): A 2-m thick normally-consolidated clay soil is resting on impermeable shale rock; a 20-m thick layer of sandy soil is placed on top of the clay to expedite consolidation process. The unit weight of the sand is 15 kN/m3 and the unit weight of the clay is 10 kN/m3. For the clay layer, the initial void ratio is 2.0, the compression index of the clay is Ce 0.40, the recompression index is C, - 0.10, and...

For the soil strata, draw diagrams indicating the total stress, pore pressure and effective stress profiles to the bottom of clay layer. Fine sand has a thickness of 6 m (FST) with saturated unit weight of 18 kN/m2. Clay has a thickness of 8 m with saturated unit weight of 14 kN/m3 The water table is located at depth of 0.7 of fine sand thickness below the ground surface (i.e. depth=0.7*FST). Fine sand will sustain capillarity (suction). Assume the same...

A 5m wide and 10m long rectangular foundation is built on a site where the soil profile consists of 3m of gravel and 4m of clay overlying rigid impermeable rock as shown in Fiqure 8. The foundation carries a surcharge loading of q-65 kN/m2 Initially the water table is 1 m below the surface of the gravel. The water table rises to the surface of the gravel slowly over a period of time and the surface loading induces an increase...
