A group of 4 point loads 3000 kN each are acting on the vertices of a rectangular area of length 5 m and breadth 3m. Determine the vertical stress at a point situated below the midpoint of the shorter side and at a depth of 6 m. Use Boussinesq's theory.

The load applied to the soil is transferred to the underground. The presence of water at soil pores and solid grains above the soil are the primary components that are responsible for the effective load transfer. Due to the load acting, the internal comp…
