Abstract

Za potrebe izvedbe podzemne garaže stambene zgrade u ulici Radnički dol u Zagrebu izvest će se duboka građevna jama, za koju je potrebna složena zaštitna konstrukcija. Na bočnim stranama jame, prema susjednoj zgradi, predviđa se izvedba armiranobetonske dijafragme kao zaštitne konstrukcije koja u nagnutom terenu ima različite karakteristične presjeke. U radu su provedene geotehničke analize za varijantu izvedbe dijafragme pridržane geotehničkim sidrima. Analizirani su reprezentativni modeli za karakteristične dubine iskopa prema susjednim građevinama programom GeoStudio 2020. Uspoređeni su varijantni betonski presjeci dijafragme, te različiti numerički modeli tla. Provedenim geotehničkim proračunima ocijenjeni su pomaci dijafragme i temeljnog tla, te momenti savijanja i sile u sidrima za razne faze iskopa građevne jame.

Abstract (english)

For the construction of the underground garage of the residential building in Radnički dol Street in Zagreb, it is planned to excavate deep construction pit, which needs complex protection structure. At lateral sides of excavation, towards the neighboring residential building, the reinforced concrete diaphragm wall is chosen as a protection structure which in sloping terrain has several characteristic cross-sections. In this Master's thesis the geotechnical analyses for the diaphragm supported by prestressed geotechnical anchors are performed. The representative models, covering characteristic excavation depths towards the neighboring buildings are analyzed by computer program GeoStudio 2020. The comparison is made for variant concrete diaphragm sections, as well as different numerical soil models. The performed geotechnical analyses evaluated the displacements of the retaining wall and the foundation soil, as well as the bending moments and forces in the anchors for various phases of excavation.
