Abstract

U diplomskom radu su obrađene bottom-up i top-down metode izvođenja podzemnih etaža. Uvodno se pristupilo zajedničkoj problematici i zaštiti građevne jame u obliku ugrađenog potpornog zida. Opisane su vrste, obilježja i ograničenja potpornog zida od čeličnih talpi, berlinskog ziđa, pilotne stijene i dijafragme. Posebna pažnja obratila se na tehnologiju izvođenja potpornih zidova te njihova zaštita od djelovanja procjedne i oborinske vode. Slijedi opis bottom-up metode, njena obilježja te uvjeti i vrste podupiranja stijenki potpornog zida kako napreduje iskop građevne jame. Podupiranje je obrađeno u obliku kosnika, razupora, zatega i geotehničkih sidara. e je opisana top-down metoda uz svoje zahtjeve i ograničenja prilikom izvođenja. U konačnici napravljena je analiza bottom-up i top-down pristupa prema SWOT analizama, kronološkom slijedu aktivnosti te prednostima i nedostatcima.

Abstract (english)

The graduate thesis deals with construction of underground floors using bottom-up and top-down approach. First, common issues and similarities are listed and protection of the construction pit in form of a embedded retaining wall is described. Next, specifics and limitations of retaining walls in form of sheet pile, king post, continuous pile and diaphragm wall are elaborated. Special attention is added to the construction technologies of retaining wall and the protection of a wall against the effects of conducted and rainwater. The thesis is continued with explanation of a bottom-up approach, its characteristics and requirements of supporting the retaining wall as the excavation of construction pit progress. Support of retaining wall is processed in the form of berm and raking props, struts and geotechnical anchors. Finally, a comparison of the bottom-up and top-down approach is made according to the SWOT analyzes, chronological order of activities and their advantages and disadvantages.
