Boussinesq's Theory

Equation and meaning

\[\sigma_{zmax} = 0.4775 \cdot \frac{Q}{{r}^{2}}\]

suub> below the point load at depth z

Variables in this formula

Q — Q
Enter this value unless it is the selected unknown.
r — Radius
Radius SI unit: m
sigma_zmax — Sigma Zmax
Enter this value unless it is the selected unknown.

How to use this calculator

  1. Leave one value emptyThe empty field is automatically treated as the unknown.
  2. Enter known values and unitsChoose N, kgf, dyn, SI or another compatible unit when available.
  3. Review the automatic answerThe result appears immediately and is substituted back into the formula to check the residual.
