These functions calculate vertical stress at a point (sigmaZ) and versus depth (sigmaZ.profile)

gamma |
vector of unit weights (pcf or kN/m^3) |
thk |
vector of layer thicknesses (ft or m) |
depth |
vector of layer bottom depths (ft or m) |
zw |
depth of groundwater table (ft or m) |
zout |
desired depth of output (ft or m): a single value |
gammaW |
unit weight of water (default = 62.4 pcf for English units; 9.81 kN/m^3 for metric units) |
metric |
logical variable: TRUE (for metric units) or FALSE (for English units) |
Either layer thicknesses or depths to layer bottoms must be specified.
Function sigmaZ outputs a three-element list giving the stresses at a specified depth:
sigmaZ.eff = effective vertical stress
sigmaZ.total = total vertical stress
u = pore water pressure
Function sigmaZ.profile outputs a four-element list giving the stress variation with depth (four vectors):
depth = depth
sigmaZ.eff = effective vertical stress
sigmaZ.total = total vertical stress
u = pore water pressure
