Question

Homework #10 A soil exploration result of a site is shown in the following figure. A building is to be constructed at that site. First, it has been proposed to raise the elevation of the ground by filling the site with 10 ft thick compacted soil at an area of 25 ft x 25 ft. The unit weight of the compacted moist soil was 120 pcf. The foundation of proposed building was constructed at the center of the compaction area and at the depth of 5 ft from the top of compacted soil as shown in the figure. Size of the foundation is 5 ft x5 ft and it carries a load of 100 kips. Please calculate the net stress increase that results due to the filling and foundation at the middle of clay layer. compacted soill fill (25 ft x 25 ft Footing 5 ft 10 t 122 per 10 ft sand Water table clay void ratio 1.6 10 118 pcf Bed Rock

    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...

    Figure P3 shows the soil profile at a site for a proposed office building. It is expected that the vertical stress at the top of the clay will increase by 150 kPa and at the bottom by 90 kPa. Assurning a linear stress distribution within the clay: (a) Calculate the consolidation settlement. You should divide the clay into five layers, compute the settlement for each layer, and then find the total settlement. Assume G = 2.7 for both sand and...
