sigmaZ: Vertical Stress at a Point

Description

Computes the vertical stress at a point. 1 October 2015

Usage

sigmaZ(gamma, thk = NA, depth = NA, zw, zout, gammaW = NA, metric)

Value

A three-element list containing: sigmaZ.eff = effective vertical stress, sigmaZ.total = total vertical stress, and u = pore water pressure

Arguments

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)
