Boussinesq Equation for Vertical Stress in Soil: Formula and Example
The Boussinesq equation estimates the increase in vertical stress at depth caused by a point load applied at the surface of an ideal elastic half-space. For a vertical point load Q, the stress increase at radial distance r and depth z is: Δσz = (3Q/2π) × z³/(r² + z²)5/2 The result is a stress increment … Read more
