Refer to the figure below. The site consists of 8 ft of sand overlying 4 ft of clay. The groundwater level is 4 ft below the ground surface. Given that a proposed footing for a building will be 10 ft by 10 ft at a depth of 2 ft below the ground surface and the load on the foundation is 800 kips, calculate the primary consolidation settlement of the clay layer. Use the 2:1 method to determine the stress distribution...

The time for 50% consolidation of a 25 mm thick clay specimen (drained at top and bottom) in the laboratory is 150 sec. How long (in days) will it take for a 3 m thick layer of the same clay in the field under the same pressure increment to reach 75% consolidation? There is an impermeable shale layer at the bottom of the clay layer in the field I. 2. Use Figure 1 for the following Compute the vertical effective...

20-ft thick fill is planned to be placed at a construction site. Ground settlement is of concern due to high compressibility of the clay layer. A consolidation test was performed on a sample collected from the center of the 15-ft thick clay layer. On the following page, e-logp curve obtained from the test is included. Estimate ground settlement based on the information provided. Hint: Don't forget to correct the curve for field conditions. Ifơ0 is within 10%...

a) Use phase diagrams to derive the relationship between; S, Co, co, e, P and P° [5] b) A footing is to be located 5ft below ground level, as shown in Figure 2 below. The base of the square footing is 8ft by 8ft and it exerts a total load of 240 tons, which includes column load, weight of footing, and weight of soil surcharge on the footing. Find the total expected primary consolidation settlement for the clay layer 115)...

For the soil profile shown below, calculate the final settlement due to the placement of the sand fill. Estimate the excess pore pressure at a depth of 1.5 m into the third clay layer 1.5 years after the fill is placed. Assume the coefficient of consolidation is Cv = 1.8 m2/yr. Fill y = 16.0 kN/m² (3m thick) Clay 1 (3m thick) Sand (0.5m thick) Clay 2 (2m thick) Sand (0.5m thick) Clay 3 (4m thick) Sand (0.5m thick) eo...

proposed for construction to cover the water shortage of government
officers’ quarters that located near to an existing 6.0 m high
concrete water tank with similar diameter. The existing water tank
