< 16 Bearing Capacity of Soils Calculators

Ultimate Bearing Capacity of Soil under Long Footing at Surface of Soil

Go Ultimate Bearing Capacity = ((Prandtls Cohesion/tan(Angle of Internal Friction))+(0.5*Dry Unit Weight of Soil*Width of Footing*sqrt(Coefficient of Passive Pressure))*(Coefficient of Passive Pressure*exp(pi*tan(Angle of Internal Friction))-1))

Safe Bearing Capacity given Net Ultimate Bearing Capacity

Go Safe Bearing Capacity = (Net Ultimate Bearing Capacity in Soil/Factor of Safety in Bearing Capacity of Soil)+(Unit Weight of Soil*Depth of Footing in Soil)

Bearing Capacity Factor Dependent on Unit Weight by Vesic's Analysis

Go Bearing Capacity Factor dependent on Unit Weight = 2*(Bearing Capacity Factor dependent on Surcharge+1)*tan((Angle of Internal Friction of Soil*pi)/180)

Net Safe Bearing Capacity given Ultimate Bearing Capacity

Go Net Safe Bearing Capacity in Soil = (Ultimate Bearing Capacity in Soil-Effective Surcharge in KiloPascal)/Factor of Safety in Bearing Capacity of Soil

Ultimate Bearing Capacity given Factor of Safety

Go Ultimate Bearing Capacity = (Net Safe Bearing Capacity in Soil*Factor of Safety in Bearing Capacity of Soil)+Effective Surcharge in KiloPascal

Angle of Internal Friction given Bearing Capacity by by Vesic's Analysis

Go Angle of Internal Friction = atan(Bearing Capacity Factor dependent on Unit Weight/(2*(Bearing Capacity Factor dependent on Surcharge+1)))

Ultimate Bearing Capacity given Depth of Footing

Go Ultimate Bearing Capacity = Net Ultimate Bearing Capacity in Soil+(Unit Weight of Soil*Depth of Footing in Soil)

Safe Bearing Capacity

Go Safe Bearing Capacity = Net Safe Bearing Capacity in Soil+(Unit Weight of Soil*Depth of Footing in Soil)
