Bearing Capacity Factor Dependent on Unit Weight Formula

What is Bearing Capacity?

In geotechnical engineering, bearing capacity is the capacity of soil to support the loads applied to the ground. The bearing capacity of soil is the maximum average contact pressure between the foundation and the soil which should not produce shear failure in the soil.
Below are few factors influencing Bearing Capacity:
Soil Strength.
Foundation Width.
Foundation Depth.
Soil Weight and Surcharge.
Spacing Between Foundations.
Earthquake and Dynamic Motion.
Frost Action.
Subsurface Voids
