B1/VM4

The solution is based on NZ standard B1/VM4, where the bearing capacity of foundation soil is given by the formula:

bearing capacity factors:

shape factors:

depth factors:

pro d/b ≤ 1:

pro d/b > 1:

inclination factors:

pro φ=0:

where:

d

-

depth of the footing bottom

b

-

width of foundation

l

-

length of foundation

c

-

undrained shear strength

H

-

horizontal component of resultant load

V

-
