Load Spreadsheet Settlement For Free

The elastic settlement of the footing in case of saturated clays is determined using the relation: S i = q B ( E s 1 ? ? ) I. S i = q B ( 1 ? ? E s ) I. S i = q ( 1 ? ? 2 E s ) I. S i = q B ( 1 ? ? 2 E s ) I.

To calculate the settlement fractions, the mean constant stresses ?konst,i are determined for all i lamellas. The total settlement is equal to the sum of the partial settlements of all lamellas. An example with 6 lamellas is shown below.

Total settlement refers to the overall change in vertical distance. Differential settlement involves an expected amount that the total settlement will vary between points over a horizontal distance, which can be caused by variations in the foundation soil profile and wall height over a certain distance.

The rate of settlement of a saturated soil is expressed by the coefficient of consolidation (cv). The rate of settlement of a soil, and hence the value of cv, is governed by two factors: the amount of water to be squeezed out of the soil; and the rate at which that water can flow out.

Immediate settlement of cohesive soils is given by S i = q B ( 1 ? ? 2 E s ) S i = H C log e ? ¯ 0 + ? ? ¯ ? ¯ 0. S i = E s ( 1 ? ? 2 ) I q B. S i = C H log e ? ¯ 0 + ? ? ¯ ? ¯ 0.

The three components of geotechnical settlement Immediate settlement (also known as elastic settlement) Consolidation settlement (or primary settlement) Creep settlement (or secondary settlement).

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) + ?t = time for which secondary settlement is to be calculated.
