The bearing capacity of soil is given by the equation. Q_a=\frac {Q_u} {FS} Qa = FSQu. in which Qa is the allowable bearing capacity (in kN/m 2 or lb/ft 2 ), Qu is the ultimate bearing capacity (in kN/m 2 or lb/ft 2) and FS is the safety factor.

WebbCohesion. The cohesion is a term used in describing the shear strength soils. Its definition is mainly derived from the Mohr-Coulomb failure criterion and it is used to describe the non-frictional part of the shear resitance which is independent of the normal stress.
