Abstract

Za potrebe izvedbe podzemne garaže na padini iznad ulice Ribnjak u Zagrebi izvest će se duboka građevna jama. Predviđa se izvedba armiranobetonske dijafragme kao zaštitne konstrukcije. U radu su provedene geotehničke analize za varijantu izvedbe dijafragme pridržane geotehničkim sidrima. Analizirano je nekoliko reprezentativnih modela za karakteristične dubine iskopa prema ulici i susjednim građevinama programom GeoStudio 2020. 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)

The deep construction pit will be excavated for the purpose of underground garage construction in the slope above the street Ribnjak in City of Zagreb. A reinforced concrete diaphragm wall is chosen as a protection structure. In this Master´s thesis the geotechnical analyses for the diaphragm supported by prestressed geotehnical anchors are performed. Several representative numerical models are analyzed by computer program GeoStudio 2020. These models cover characteristic excavation depths towards the street and neighboring buildings. The performed analyses enabled the estimate od diaphragm and ground displacements, as well as bending moments and anchor forces for various phases of pit excavation.
