Module 4 : Design of Shallow Foundations
Lecture 19 : Settlement [ Section19.3 : Sources of settlement analysis ]
   
  Settlement analysis
Elastic compression of the foundation on the underlying soil
Plastic compression of the soil
Ground water table lowering
Vibration due to pile driving, blasting and oscillatory machinery. this is more predominant in sand
Seasonal swelling and shrinkage in expansive soils.
Surface erosion creep or landslides in earth slopes.
Miscellaneous sources such as collapse of soil mining subsidence, underground erosion, earthquake loading and adjacent excavation.
 
Settlement of a rigid load resting on an elastic and isotropic material.
 

is the net applied pressure at the foundation

B=width of the foundation

=coefficient due to the effect of embedment

=coefficient due to the effect of the shape.

Corrections

=correction factor for lateral strain
