Sažetak
The paper presents the design of deep excavation support system in an urban environment. Excavation is carried out in the vicinity of surrounding buildings whose structural stability must be ensured during the execution of the construction works. The 60 cm thick diaphragm wall supported by the two rows (17.00 m and 18.25) of geotechnical anchors was selected as an exca-vation support system. The approximate floor plan dimensions of the diaphragm wall are 81x118 m, and the maximum excava-tion depth is 10.5 m. An additional challenge in designing the diaphragm wall is the presence of groundwater, whose maximum level is observed at a depth of approximately 5.8 m. In order to ensure the execution of construction works in dry conditions, a system of drainage trenches and wells is designed at the bottom of the pit. The diaphragm wall is designed in accordance with Eurocode 7.
