Ngamma: Bearing capacity factor Ngamma

In maxgav13/GMisc: Miscellaneous Functions for Geology (and its areas)

Bearing capacity factor Ngamma

Description

Taken from "geotech" package. Calculate the bearing capacity factor Ngamma using either the Terzaghi or Vesic methods.

Usage

Ngamma(phi, case = "general", method = "Terzaghi")

Arguments

phi	Friction angle in degrees
case	"general" or "local" to indicate general or local shear failure ("general" is default)
method	"Terzaghi" or "Vesic" ("Terzaghi" is default)

Value

Bearing capacity factor
