Abstract
Odron na stijenskim kosinama je iznenadan te kao takav može imati razoran i po ljudski život vrlo opasan ishod. Infrastrukture poput prometnica, željezničkih pruga, industrijskih postrojenja, kamenoloma, naselja i sličnih tome, predstavljaju rizični objekt u području opasnosti od odrona. Državna cesta DC3, točnije njezina dionica Orehovica – Školjić, na lokaciji Banska Vrata (Rijeka) izložena je opasnosti od odrona te predstavlja rizični objekt kojeg je potrebno zaštititi. Na toj su lokaciji zabilježeni česti odroni stijenske mase. Zadnji veći odron stijenskog materijala zabilježen je 27. siječnja 2020. godine. Iz 3D oblaka točaka, koji prikazuje stijensku kosinu, koristeći program CloudCompare definirana je zona potencijalne nestabilnosti odrona te je iz te zone izvučen analizirani profil. Na profilu je provedeno modeliranje odrona metodama sjedinjene mase i diskretnih elemenata – kruto tijelo. Za modelirane su odrone predložena rješenja zaštite prometnice od odrona primjenom fleksibilne barijere. Definirano je kakvi se sve tipovi pasivne zaštite razlikuju, njihovo područje primjene, postupak dimenzioniranja, prednosti i nedostaci. No, prije svega je opisana sama nestabilnost odrona. Mehanika kretanja i udara odrona te zakonitosti i promjene koje su aktualne u tim fazama.
Abstract (english)
Rockfall at rocky slopes is sudden and as such can have a devastating and very dangerous outcome for human life. Infracture such as roads, railways, industrial plants, quarries, populated places and similar represent a risky object in the area of rockfall hazards. The state road DC3, more precisely its section Orehovica – Školjić, at the location Banska Vrata (Rijeka) is exposed to the danger of rockfall and needs to be protected. Frequent landslides were recorded at this location. The last major landslide of rock material was recorded on January 27, 2020. From the 3D point cloud, which shows the rock slop, using the CloudCompare program, the zone of potential instability of the rockfall was defined and the analyzed profile wasextracted from the zone. Rockfall modeling was performed on the profile using the lumped mass and discrete element – rigid body methods. For modeled landslides, solutions for road protection from rockfall have been proposed using a flexible barrier. It is defined what types of passive protections there are, their area of application, slizing procedure, its pros and cons. The instability of the rockfall itself is described. The mechanics of movement and impact of rockfall and the law and changes that are current in the phases.
