Stress increase (q

_{z}) at midpoint of compressible layer due to foundation load (q) is calculated by 2/1 method as follows:q

_{z}= (q x B x L) / [(B + z) x (L + z)]q

_{z}= {{temelAltiGerilmesi | round:2}} x {{tg | round:2}} x {{tl | round:2}} / [({{tg | round:2}} + {{ortaDerinlik | round:2}}) x ({{tl | round:2}} + {{ortaDerinlik | round:2}})]q

_{z}= {{stresArtisi | round:2}} kPaCompressible layer thickness considering foundation depth (D

_{f}) is calculated as H = {{sikisabilirTabakaKalinligi | round:2}} m. So;s

_{oed}= H x m_{v}x q_{z}= {{sikisabilirTabakaKalinligi | round:2}} x {{mv | round:2}} x 10^{-5}x {{stresArtisi | round:2}}s

_{oed}= {{soed | round:3}} m = {{soedCM | round:1}} cmSkemton ve Bjerrum correction factor for {{ kilTipiismi }} is selected as {{sbcf | round:2}} and consolidation settlement is calculated as;

s = μ x s

_{oed}s= {{sbcf | round:2}} x {{soedCM | round:1}} = {{s | round:2}} cm

In order to calculate the consolidation settlement in {{t | round:0}} months, Tv parameter should be calculated first.

Since drainage path is {{drenajTipiismi}}, H

_{dr}= {{sikisabilirTabakaKalinligi}} / {{drenajTipi}} = {{drenajYolu}} mT

_{v}= c_{v}x t / H_{dr}^{2}T

_{v}= ({{cv}} x 10^{-8}) x ({{t | round:0}} x 30 x 24 x 60 x 60) / {{drenajYolu}}^{2}T

_{v}= {{tv | round:5}}After calculating T

_{v}parameter, U (%) can be calculated as follows:0 ≤ U(%) ≤ 60 → U(%) = 100 x (4 x T

_{v}/ π)^{0.5}60 < U(%) ≤ 100 → U(%) = 100- 10

^{(1.781-Tv)/0.933}U(%) = {{u | round:2}}

Finally, results are calculated and tabulated as follows:
