Nq: Bearing capacity factor Nq

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

Bearing capacity factor Nq

Description

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

Usage

Nq(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
