Overburden pressure
From Wikipedia, the free encyclopedia
(Redirected from Lithostatic pressure)
Overburden pressure, lithostatic pressure, and vertical stress are terms that denote the pressure or stress imposed on a layer of soil or rock by the weight of overlying material.
The overburden pressure at a depth z is given by
- <math>p(z) = p_0 + g \int_{0}^{z} \rho(z) \, dz</math>
where ρ(z) is the density of the overlying rock at depth z and g is the acceleration due to gravity. p0 is the datum pressure, like the pressure at the surface.
