The total settlement of the ground consists of 3 components: immediate settlement (commonly referred to as elastic settlement, although this is a misnomer), consolidation settlement (or primary settlement) and creep settlement (or secondary settlement).

Total settlement for cohesive soils are generally estimated by the sum of immediate settlement, primary consolidation and secondary compression, where immediate settlement usually constitutes a significant portion of the total settlement.

Settlements refer to the soil's movement in the vertical direction typically induced by stress changes.Since soil particles are practically incompressible, consolidation settlements is caused by a reduction in voids due to gradual squeezing out of water.

Worked Example Calculation of Settlement of Shallow Foundations at the CenterData. Dimensions of foundation 1.5m x 2m.A1 = 0.934. A2 = m' / n' (m'2 +n'2 + 1)0.5 F1 = (1/03c0)A0 + A1 = (1/03c0)0.760 + 0.934 = 0.539. F2 = (n'/203c0) tan-1A2If = 0.755. Foundation Settlement.

Settlement is simply caused by soil displacement due to shifting. Most soil, especially top layers of soil that are still in the active zone, are very susceptible to movement. Soil is not static. This shifting soil creates air pockets beneath your foundation, displacing the weight of your house.

This happens because soil is a two-phase material, comprising soil grains and pore fluid, usually groundwater.The effects of consolidation are most conspicuous where a building sits over a layer of soil with low stiffness and low permeability, such as marine clay, leading to large settlement over many years.

What is Settlement? Settlement is the downward movement of the ground (soil) when a load is applied to it. The load increases the vertical effective stress exerted onto the soil. This stress, in turn, increases the vertical strain in the soil. This increase in vertical strain causes the ground to move downward.
