# bearingPressure: Bearing Pressure In geotech: Geotechnical Engineering

## Description

This function computes the gross bearing pressure that a soil would experience due to a foundation.

## Usage

 `1` ```bearingPressure(P, B, L, D, Dw, metric, gammaW = NA, gammaC = NA) ```

## Arguments

 `P` Vertical gross column load (lb or kN) `B` foundation width (ft or m) `L` foundation length (ft or m) `D` Depth of foundation (ft or m) `Dw` Depth of groundwater table below foundation base (ft or m) `metric` logical variable: TRUE (for metric units) or FALSE (for English units) `gammaW` unit weight of water (default = 62.4 pcf for English units; 9.81 kN/m^3 for metric units) `gammaC` unit weight of concrete (default = 150 pcf for English units; 23.6 kN/m^3 for metric units)

## Details

• Either SI or English units can be used, but must stay consistent.

• When specifying the length and width, L should be the longer of the two lengths.

• For a continuous (strip) foundation, specify L = 1 and specify P as the load per unit length.

• When the groundwater table is deep or unknown, set Dw >= D.

## Value

Gross bearing pressure of footing (psf or kPa)
