Design of the Roxanich vinery foundation pit in Motovun

Prilikom izgradnje građevinskih objekata javlja se potreba za izvedbom građevinske jame. Kako bi se osigurao siguran rad unutar jame te stabilno temeljenje buduće konstrukcije, pokos građevinske jame potrebno je stabilizirati podgradnim i potpornim sustavima. Kako je kvaliteta stijenske mase predodređena in situ uvjetima koji su daleko od kontroliranih, podgradnim sustavom se poboljšavaju njezina svojstva te se postiže da stijenska masa “nosi samu sebe”. U ovom radu dan je pregled sustava ojačanja kojima se stabiliziraju pokosi stijenske mase. Opisani su empirijski kriteriji za proračun čvrstoće i deformabilnosti stijenske mase, a pomoću računalnog programa RS2 provedena je analiza stanja naprezanja i deformacija građevinske jame vinskog podruma Roxanich. Prikazani su dobiveni rezultati analize te je na kraju rada dan tehnički opis izvedbe jame.During the construction of building, there is usually a need for construction of a foundation pit. In order to ensure a safe work environment within the pit and a stable foundation of the future construction, the cut of the construction pit must be stabilized with substructure and supporting structures. Since quality of the rock mass is predisposed with in situ conditions, with no possibility to be controlled, the substructures and supporting structures improve its properties, which ensures that the rock mass "carries itself". This paper gives an overview of supporting structures that stabilize rock mass cuts. Empirical criteria for the determination of strength and deformability of the rock mass have been described and a stress-deformation analysis of the Roxanich Viner foundation pit using the RS2 computer program has been carried out. The results of the analysis are presented and the technical description of the construction of the pit is provided at the end of the thesis
