Abstract
Konsolidacija tla je proces vremenskog smanjenja volumena saturiranih tala niske vodopropusnosti uslijed disipacije porne vode uzrokovanog opterećenjem. Koherentna tla niske hidrauličke vodljivosti neophodno je tretirati kako se nakon izvedbe ne bi javila potencijalna oštećenja konstrukcija uzrokovana slijeganjima. S obzirom da se proces konsolidacije može se odvijati u dugom vremenskom periodu nakon primjene opterećenja nasipom potrebno je primijeniti odgovarajuće metode kojima se omogućuje brži razvoj vremenskih deformacija. U radu su prikazane osnovne karakteristike i opravdanost primjene predopterećenja tla, metode vibracijskog punjenja i primjene prefabriciranih vertikalnih drenova te način određivanja utjecaja navedenih pristupa na razvoj deformacija u tlu uzrokovanih opterećenjem s površine. U radu je prikazan pristup rješavanja problema dugotrajnih slijeganja opterećenih krutih prašinastih tala. Prikazan je način modeliranja predviđenog poboljšanja tla šljunčanim pilotima ispod nasipa željezničke pruge te je provedena parametarska analiza utjecaja duljine i osnog razmaka šljunčanih pilota na razvoj vremenskih slijeganja. Analize trenutnog i vremenskog slijeganja temeljnog tla provedene su u programskom paketu FLAC 7.0. Temeljem rezultata analize slijeganja tla odabrana je optimalna geometrija poboljšanja za koju je izrađen troškovnik radova i nacrtna dokumentacija.
Abstract (english)
Soil consolidation is a time depended process of a gradual reduction in volume of a fully saturated soil of low permeability due to the drainage of pore water set up by a load uppon a soil. It is neccecary to treat coherent soils with low hidraulic conductivity to evade potencial post-construction structural damage caused by settlements. Giving the fact that the consolidation process can develop throught a long period after the application of loads by an embankment it is neccecary to use appropriate methods which enable faster development of time deformations. In the paper, elementary characteristics and the feseability of use of a surcharge, method of vibroflotation and the use of prefabricated vertical drains and the way of determining the influence of said approches on the development of soil deformation caused by surface loads is shown. The approach of solving a long-term settlement problem of loaded stiff silty soils and a method for modeling the stipulated soil improvement by means of stone columns below an embankement is shown in the paper. A parametric analysis was conducted to show the influence of length and axial spacing of stone columns on the development of long-term settlements. Cost estimate and blueprints were made for the optimal geometry of soil improvement that was selected on the basis of the results of the settlement analysis.
