stressVertical: Vertical Stress Calculations In geotech: Geotechnical Engineering

Description

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

Usage

 ```1 2 3``` ```sigmaZ(gamma, thk = NA, depth = NA, zw, zout, gammaW = NA, metric) sigmaZ.profile(gamma, thk = NA, depth = NA, zw, zout = NA, gammaW = NA, metric) ```

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)

Details

Either layer thicknesses or depths to layer bottoms must be specified.

Value

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
