a. At Wlmat depiI W ld you place the mat to make this a fully compensated foundation? b. What should be the factor of safety if the mat is placed at 3.0 m depth? a A 15 m X 20 m mat foundation shown in Figure P10.7 car- ries a building load of 36 MN and is placed at 3.0 m depth below the ground level. a. Find the net applied pressure on the underlying ground. The consolidation tests show that the preconsolidation pressure at the middle of the clay layer is 210 kN/m². b. Is the clay overconsolidated?

A concrete square footing 1.5 m x 1.5 m has a total depth of 500 mm. It supports a rectangular column 300 mm x 400 mm. If the allowable normal stress of concrete is 4 MPa. What is the maximum axial load (in kN) the column can carry? Do not include units in final answer. Answer in 3 decimal places. A concrete square footing 1.5 m x 1.5 m has a total depth of 425 mm. It supports a rectangular column 300 mm x 280 mm. If the punching shear strength of concrete is 2.2 MPa. What is the maximum axial load (in kN) the column can carry? Do not include units in final answer. Answer in 3 decimal places.

Q3- A raft foundation (12 * 8) m carrying a net pressure of 183 kN/m² is located at a depth of 3.8 m below the surface in deposit of dense sandy gravel 6 m deep. The water table is located at a depth of 4.3 m. Below the sandy gravel is a layer of clay 3.8 m thick which in turn is underlain by dense sand. The value of mv for the clay is 0.28 m²/MN. Determine the settlement below the center and below the corner of the raft due to consolidation of the clay.
