Stress distribution in soil due to a point load can be analyzed using Boussinesq’s method, which provides a way to calculate how stresses spread within a soil mass. The concept of a “stress bulb” represents the area beneath the surface where the stress decreases with depth and distance from the point of load application. Boussinesq’s method assumes an elastic, isotropic, and homogeneous medium, and it helps in visualizing how vertical stress from a surface load disperses in a bulb-like pattern, with higher stresses near the load and diminishing stresses as the depth and lateral distance increase.
