(b) A site investigation has revealed that the site is underlain by a thick layer of firm CLAY and the water table is at the ground surface. The clay has a unit weight of 18kN/m and a characteristic undrained strength (Cuk) of 85KN/m?. Shallow rectangular padfoundations (1.5m wide x 2.5m long) founded at a depth of 2.5m below ground level are proposed for the structure. You are required to determine if the pad foundation can accommodate a permanent action of 500kN (which includes the self-weight of the foundation) combined with a variable action of 200KN. I.State the appropriate partial factors for the soil parameters and determine the design values for the soil parameters II.Determine the total design value of the actions III.Demonstrate that the ultimate bearing resistance is acceptable
