Settlement Under Foundations Calculations

 
The approximate relationship between loads on foundations and settlement is:
 
 
where:
 
q = load intensity, lb/ft2 (kg/m2)
P = settlement, in (mm)
d  = depth of foundation below ground surface, ft (m)
b = width of foundation, ft (m)
C1= coefficient dependent on internal friction
C2 = coefficient dependent on cohesion

The coefficients:

 
C1 and C2 are usually determined by bearingplate loading tests.
