Designed solution for the foundation pit protection of the underground garage in Vlajkovićeva street

Abstract

Within the design of the underground garage in Vlajkovićeva Street, various variant solutions for the foundation pit protection and neighboring buildings were considered. It is necessary to meet the condition that the stability of the sides of the excavation is ensured during the works and later in the operation of the facility, as well as to enable quality execution of works. Based on the performed analyzes, it can be concluded that the production of "single" diaphragm lamellas with the installation of prefabricated elements and the construction of a protective wall between them in two phases in specific conditions is the most favorable solution.
