A soil profile consists of 2 m of sand overlying 10 m of clay. The water table is located at 1 m below the groundsurface. It can be assumed that the degree of saturation of the soil above the ground water table is 0% and thedegree of saturation of the soil below ground water table is100%.Other relevant data are given below:-The dry density and the saturated density of sand are 1650 kg/m3and 1760 kg/m3respectively.-The dry density and the saturated density of clay are 1630 kg/m3and 1720 kg/m3respectively.-Due to the placement of a footing, the stress increase at 1.5 m depth is 15 kPa.-Due to the placement of a footing, the stress increase at 3 m depth is 12.5 kPa.Based on the given information, complete the following tasks:Draw a sketch of the ground condition.Calculate the dry unit weight and saturated unit weight for both sand and clay.Calculate Total Stress, Hydrostatic Pore Water Pressure, Excess Pore Water Pressure and Effective Stressvalues in kPa at 1.5 m depth BEFORE the placement of the foundation.Calculate Total Stress, Hydrostatic Pore Water Pressure, Excess Pore Water Pressure and Effective Stressvalues in kPa at 1.5 m depth IMMEDIATELY AFTER the placement of the foundation.Calculate Total Stress, Hydrostatic
