Question

Describe conditions for developing the ultimate bearing capacity equation.

Expert Solution

Step 1

Conditions for developing the ultimate bearing capacity equations are as follows:

Footing is shallow.
Base of foundation is rough.
Failure is General shear failure.
Footing is continuous or strip footing.
At the time of failure soil reaches plastic equilibrium.
The stress zone of the soil extends up to foundation level only but not up to ground level.
The shear resistance of the soil above the foundation level is ignored, which means only base resistance if considered and side resistance is ignored.
The soil above the base of foundation is removed and replaced by an equivalent surcharge.
Load is vertical and concentric.
Ground surface is horizontal.
Water table is beyond the zone of influence of stressing. It means effect of water table is not considered.
