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.

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

In geotechnical engineering, settlement is defined as the downward vertical movement of the ground due to changes in stresses within it. Excessive ground movements can cause damage in buildings, structures and transport infrastructure, from bridges and tunnels to road pavements and railways.

?H = ?Hi + U ?Hc + ?Hs. ?H = total settlement, ?Hc = consolidation settlement, ?H = secondary compression, U = average degree of consolidation. Generally, the final settlement of a foundation is of interest and U is considered equal to 1 (i.e. 100% consolidation)

The primary consolidation settlement can be calculated from the coefficient of volume compressibility mv, which can further lead to the Young's modulus E? = (1 + v?)(1 ? 2v?)/mv(1 ? v?), with an assumed Poisson's ratio v?.

When soil is loaded undrained, the pore pressures increase. Then, under site conditions, the excess pore pressures dissipate and water leaves the soil, resulting in consolidation settlement. This process takes time, and the rate of settlement decreases over time.
