Abstract

Slijeganje tla, tj. vertikalna deformacija, jedno je od dva najbitnija zahtjeva za stabilnost i sigurnost strukture, a ovisi o stišljivosti i konsolidaciji tla. Konsolidacija je proces postupne promjene volumena, tj. njegovog smanjenja, prilikom izlaska vode iz pora uslijed stalnog opterećenja. Dakle, ovisi o nanesenom opterećenju, propusnosti te uvjetima drenaže. Konsolidacija i stišljivost
tla određuju se edometarskim pokusom, a prikazuju se edometarskom krivuljom koja ovisi o koeficijentu pora i efektivnom naprezanju. Ukoliko je naneseno opetrećenje (trenutno efektivno naprezanje) manje od najvećeg efektivnog naprezanja kojem je tlo bilo izloženo u svojoj povijesti, radi se prekonsolidiranom tlu, a ako je trenutno efektivno naprezanje ujedno i najveće kojem je tlo ikada bilo izloženo radi se o normalno konsolidiranom tlu.

Abstract (english)

Settlement of the soil, i.e. vertical deformation, is one out of two most important requirements for the stability and safety of the structure, and for it, compressibility and consolidation of soils need to be considerated. Consolidation of soils is a process of progressive volume changes with out-flow of pore water during constant compression. Therefore, it depends on inflicted load, permeability and drainage conditions. Consolidation and compressibility of soils are determined from oedometer test, and are shown on a compression curve which is obtained by pressure-void ratio relationship. A soil is overconsolidated soli, if its maximum effective stress to which the soil has been subjected in its stress history exceedes the existing effective stress in the soil. Furthermore, a soil is normally consolidated soil, if the existing effective stress in the soil is its maximum effective stress to which the soil has been subjected in its stress history.
