A rectangular foundation 2 m x 3 m shown in Figure 1, transmits a pressure of 360 kN/m to the underlying soil. Determine: a) The vertical stress increase at a point I m vertically below a point lying outside the loaded arca, I m away from a short edge and 0.5 m away from a long edge. Use Boussinesq's theory (m & n Approach). S 2 m Figure 1 P T 3m R Q + b) The increase in vertical pressure at a point I m vertically below point R using Newmark's influence chart.
