sigmaX.profile: Horizontal Stress Profile (Lateral Earth Pressure)

Description

Calculates the horizontal stress profile. 1 October 2015

Usage

sigmaX.profile(
  gamma,
  thk = NA,
  depth = NA,
  K,
  zw,
  zout = NA,
  gammaW = NA,
  metric
)

Value

A four-element list containing four vectors: depth = depth, 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)

K

= vector of layers' lateral earth pressure coefficients

zw

= depth of groundwater table (ft or m)

zout

= desired depths of output (ft or m): defaults to critical locations in the profile (the top and bottom of the profile, layer interfaces, and the groundwater table) [recommended]

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)
