A high rise building is being designed at the site. A detailed site investigation reveals that the site consists of 18 m of cohesion less soil over 10 m of soft clay overlying a hard rock. The water table is at the surface. Solve Problem. *If you feel that the conditions are insufficient, please refer to the other issues I have posted. 

Problem 4:Detailed analyses show that in the clay layer, vertical stresses induces increases in the horizontal and shear stresses. The increase in horizontal and shear stresses are 50% and 10% of vertical stress, respectively (positive shear stress is applied at the horizontal plane). Determine the major and minor principal stresses acting at the middle of the clay layer after the building is constructed. Use 2:1 approach to calculate the vertical stress. Assume that the building is square in shape.
