Problem 3: Determine the total settlement of the 10' x 8' foundation. 120 kip 4' -115...
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...
