Abstract

U ovom diplomskom radu obrađena je tema ojačanja temelja prilikom obnove zgrada. Prvo je dan uvid u utvrđivanje potreba za ojačanjem te koji su sve razlozi zbog kojih se temelji ojačavaju. Zatim su navedeni različiti načini ojačanja poznati iz literature ili prakse. Ti načini obuhvaćaju ojačanje temelja, od proširenja temelja, preko ojačanja pilotima do kombinacije temeljne ploče i pilota. Dan je pregled i u metode koje se koriste za ojačanje temeljnog tla, prvenstveno mlazno injektiranje te na koji način se izvode. Navedeni su određeni propisi u Republici Hrvatskoj koji su vezani uz unapređivanje svojstava građevine i prema kojima se klasificiraju geotehničke konstrukcije. Na primjeru obnove zgrade u Zagrebu prikazan je tijek utvrđivanja stanja tla i temelja. Na ostalim primjerima, također zgrada koje se obnavljaju u Zagrebu, objašnjeni su neki od načina temeljenja koji su navedeni te zašto je odabran određeni način i koja je tehnologija izvođenja.

Abstract (english)

This thesis deals with the topic of strengthening the foundations during building renovation. First, an insight is given into the determination of the need for strengthening and what are all the reasons why the foundations are strengthened. Then, different methods of reinforcement known from literature or practice are listed. These methods include strengthening the foundation, from widening the foundation, through strengthening with piles to a combination of foundation slab and piles. An overview is also given of the methods used to strengthen the foundation soil, primarily jet grouting, and how they are performed. There are listed certain regulations in the Republic of Croatia which are related to the improvement of building properties and according to which geotechnical constructions are classified. The process of determining the condition of the soil and foundation is shown on the example of building renovation in Zagreb. On other examples, also including buildings that are being renovated in Zagreb, some of the foundation methods that have been mentioned are explained; why a certain method was chosen and what is the construction technology.
