My soil has the following profile with depth: 0-10 ft gammat = 115 pcf 10-30 ft gammasat = 98 pcf 30-55 ft gammasat = 110 pcf where gamma is the unit weight The water table is at a depth of 10 ft. Plot the total stress, effective stresses, and pore pressure versus depth. Show the calculations, and assume there is no capillarity.
A uniform loading of 150kPa is applied at a 28 m Χ 28 m area. Please calculate the consolidation settlement of the clay layer used the middle of the clay layer to estimate the stress increment with the influence factor method). Cc = 0.4, Cs = 0.04, preconsolidation stress is 150 kPa and unit weight of water is 10 kN/m3. What is the settlement at the corner and center of the loading? What is the differential settlement between the corner and the center?

Dry Sand H, Groundwater Table Clay H2 Refer to the soil profile shown. Given H1 = 9.48 m., and H2 = 4.41 m. If the ground water table rises by 2.94 meters, determine the change in effective stress (numerical value only, in kPa) at the bottom of the clay layer. Properties of dry sand: Gs = 2.58, e = 0.67. Properties of clay: Gs = 2.74, e = 0.87. Round off to two decimal places.
