Unit Weight of Soil given Value of Bearing Capacity Factor Formula Elements

Variables
Unit Weight of Soil
Unit Weight of Soil mass is the ratio of the total weight of soil to the total volume of soil.
Symbol: γ
Measurement: Specific WeightUnit: kN/m³
Note: Value should be greater than 0.
Ultimate Bearing Capacity
The Ultimate Bearing Capacity is defined as the minimum gross pressure intensity at the base of the foundation at which the soil fails in shear.
Symbol: qf
Measurement: PressureUnit: kPa
Note: Value should be greater than 0.
Cohesion of Soil
Cohesion of Soil is the ability of like particles within soil to hold onto each other. It is the shear strength or force that binds together like particles in the structure of a soil.
Symbol: Cs
Measurement: PressureUnit: kPa
Note: Value should be greater than 0.
Depth of Footing
Depth of Footing is the longer dimension of the footing.
Symbol: D
Measurement: LengthUnit: m
