Bearing Capacity for Purely Cohesive Soil given Unit Weight of Soil Formula Elements

Variables
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.
Effective Surcharge in KiloPascal
Effective Surcharge in KiloPascal also called as surcharge load refers to the vertical pressure or any load that acts over the ground surface additional to basic earth pressure.
Symbol: σs
Measurement: PressureUnit: kN/m²
Note: Value should be greater than 0.
