The value of Nc and Nq are same for Meyerhof, Hansen and Vesic method, while subscripts for N? identify author, i.e. N ?(H) = valued by Hansen etc.

The ultimate bearing capacity qf and net ultimate capacity are connected by following relation:
qf = qnf + ?? (or) qf = qf ? ??
where ?? is effective surcharge at base level of foundation.

The essential difference in Vesic?s and Hansen?s procedure are i) use of slightly different values of Ny and ii) a variation on some of Hansen?s inclination, base and ground factors.

During state of shear failure (plastic equilibrium), following principal stress relationship exists ?1 = ?3 tan2 ? + 2c tan ?
for cohesion-less soil,?1 = ?3 tan2 ?.

For clayey and silty soils and for loose medium dense sandy soils with N < 15, a 450 mm square plate or concrete block shall be used.

Punching shear may occur in relatively loose sand with relative density less than 35 %.

The allowable maximum settlement for warehouse type of structure is 50 mm.

The effect of water table is taken into account in form of correction factor W? applied to wedge term.

The values of N? for ? of 34° and 48° are original Terzaghi values which were used by Bowles to back compute Kp?.

In 1986, Lio and Whitman gave following expression for
Normalizing factor C n:
C n = ? (100/??).
