Example $1-$ Point load

A concentrated load of $400kN$ acts on the surface of a soil.

Determine the vertical stress increments at points directly beneath the load to a depth of $10m.$

Take $z$ values as $0\mathrm{.}5m,1\mathrm{.}0m,2\mathrm{.}5m,5\mathrm{.}0m,7\mathrm{.}0m$ and $10\mathrm{.}0m.$

Use the chart $($slide $9).$
