Abstract

The presented study focuses on field observations and a 3D numerical analysis of open-cut excavations adjacent to a building supported by inclined struts. The performance of the struts in carrying the building loads and decreasing the deflections is investigated. Struts reduce the amount of deformations and also create a corner effect similar to the diaphragm walls corner. The influence of the distance between the struts is studied and the optimum struts interval is proposed. The most effective configuration of struts installation in reducing the deflections and building damage is proposed. A displacement-based design guideline is also presented based on the results of numerical studies.

Secondary title: 3D odziv izkopa varovanega z nagnjenimi oporniki v bližini zgradb
Secondary abstract: Predstavljena študija se osredotoča na terenska opazovanja in 3D numerične analize izkopa, varovanega z nagnjenimi razporami v bližini zgradb. Raziskan je učinek opornikov na prenašanje obtežb in zmanjšanje upogibov. Oporniki zmanjšujejo vrednosti deformacij in ustvarijo tudi kotni učinek podoben kot v vogalu diafragm. Raziskovan je vpliv razdalje med oporniki in predlagan optimalni razmik med oporniki. Predlagana je najbolj učinkovita konfiguracija vgradnje opornikov za zmanjševanje deformacij in poškodb zgradbe. Na podlagi rezultatov numeričnih študij so predstavljene smernice za projektiranje na osnovi pomikov.
