Bearing Capacity Factor Dependent on Surcharge for Local Shear Failure Formula

What is Surcharge?

Surcharge is the additional load on the soil which may be created due to any overlying structure or any moving object.Total stress on the surface of the soil is because of the surcharge only. So total stress is equal to the surcharge q. σ = q. No water present above this plane, hence pore water pressure is zero.
