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.

The total settlement of a loaded soil has three components: Elastic settlement, primary consolidation, and secondary compression. Elastic settlement is on account of change in shape at constant volume, i.e. due to vertical compression and lateral expansion.Secondary compression is on account of creep-like behaviour.

H = Thickness of the field consolidating stratum at the end of primary consolidation. Commonly initial thickness is used unless the primary consolidation is very large. Say more than 10% of initial thickness. t2 = t100(f) + 0394t = time for which secondary settlement is to be calculated.

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.

In geotechnical engineering , settlement is defined as the vertical movement of the ground, generally caused be changes in stresses within the earth.Settlement is most likely to occur when increased vertical stresses are applied to the ground on or above soft or loose soil strata.

Consolidation is the process of dissipation of excess pore pressure. Due to the dissipation of excess pore pressure, the foundations tend to settle. This settlement is known as consolidation settlement.
