A uniformly distributed load of (300 + 2) kPa is applied to a 15m x 12m rectangular area on the surface of the soil profile shown in the figure opposite. The thickness of the coarse sand layer is 5m and the thickness of the clay layer is h = (5 + 2/1) ₁ +2)m. The void ratio of the course sand is e = 0.6, and the water table is located at the top of the clay layer, as shown in the figure. Water table V (a) Determine the compression index. recompression index, and preconsolidation pressure of the soil. (8 Marks) Aot 3m Coarse sand e=0.6 Impervious Rock Pressure (kPa) 20 40 80 160 320 640 1280 20 Clay Undisturbed samples of the clay were taken from the mid-layer of the clay prior to application of the load, and consolidation tests resulted in the pressure versus void ratio data as given in the table opposite. Void ratio 0.895 0.887 0.879 0.869 0.852 0.811 0.722 0.781 5m h The coefficient of consolidation for the clay sample was estimated to be 0.001 cm²/s from the consolidation test. (c) How much settlement would you expect to occur 5 years after application of the load? (6 marks) (b) The water content of the clay sample taken from middle of the clay layer was w = (30+)%. Estimate the total consolidation settlement for the clay layer under the centre of the loaded area. Use 2:1 method for calculating the increase in vertical stress due to the applied load.
