v = z+Pa (measured in Mega Pascal)
v = z+Pa (measured in Mega Pascal)
:where is the unit weight of the overlaying rock [mN/ m<sup>3</sup>3].
where is the unit weight of the overlaying rock [mN/ m3].
:z is the depth to point below surface [m].
:Pa is the atmospheric pressure (usually neglected = 0).
z is the depth to point below surface [m].
Pa is the atmospheric pressure (usually neglected = 0).
In case the vertical stress is caused by multiple layers of different rock types, it can be estimated using the following formula:
In case the vertical stress is caused by multiple layers of different rock types, it can be estimated using the following formula:
v = aza+ bzb+czc...
v = aza+ bzb+czc...
:where a, b, and c represent different layers.
where a, b, and c represent different layers.
