Secondary title: Analysis of berth 7 in the port of Koper with the feasibility study for the deepening of seabed
Secondary abstract: Since 1957 the Port of Koper has been constantly developing. Constant expansion and optimization of the existing infrastructure is essential due to the need for competitiveness. Because of the recent arrival of the new generation of post-panamax ships with deeper drafts, there is now the necessity to deepen the bottom of the seabed from 12 m to 15 m. The deepening of the seabed near coastal structures has also negative impacts on costal structures, which need to be examined. This thesis presents different ways of 2D modeling of coastal structures. Especially carefully is discussed the new element in the FE program Plaxis called "Embedded pile row". When using classical linear finite element it happens that in virtual crossing points of vertical and diagonal elements, internal forces are transferred between elements. This happens, because of the virtual unrealistic connection between them. In addition, the "Embedded pile row" element is very suitable for modeling piles. It allows determining the course of bearing capacity of the shaft and the bearing capacity of the toe of the pile. In the first part, the behavior of EPR element is compared to the results of static loading tests, which took place in the Port of Koper. At the same time, is it also analyzed the effect of different parameters that must be determined using EPR elements. In the second part of the thesis, knowledge earned in the first part is used for modeling the deepening of the pier 7A from 12 m to 15 m. Later the model with EPR elements is compared with basic line tipe element model.

Abstract (ePrints): Luka Koper se razvija že vse od leta 1957. Zaradi potrebe po konkurenčnosti konstantno teži k širjenju in optimizaciji obstoječe infrastrukture. Tudi sedaj, ko se pričakuje izgradnja tretjega pomola, je potrebno poskrbeti, da se bo tovor nemoteno pretovarjal na obstoječih pomolih. Ob prihodu novih ladij post-panamax generacije z globljim ugrezom, se je pojavila potreba po poglobitvi dna na kontejnerskemu terminalu iz 12 m na 15 m. Poglobitev morskega dna v bližini obalne konstrukcije ima nanjo tudi negativne vplive, ki jih je potrebno raziskati. V tej diplomski nalogi so predstavljeni različni načini 2D modeliranja obalne konstrukcije. Posebej natančno so obravnavani novi elementi v programu Plaxis, poimenovani »Embedded pile row« (EPR). Ob uporabi klasičnih linijskih končnih elementov se v 2D modelih zgodi, da se v točkah navideznega križanja vertikalnih in poševnih elementov notranje sile prenašajo kot posledica navideznega stika kolov. Z uporabo EPR elementov teh težav ni. Poleg tega so zelo primerni za modeliranje kolov, saj nam omogočajo natančno določitev poteka nosilnosti po plašču in pod nogo kola. Obnašanje EPR elementov je v prvem delu diplomske naloge primerjano z rezultati statičnega obremenilnega testa, ki je bil izveden v Luki Koper. Hkrati so bili analizirani tudi vplivi parametrov, ki jih moramo določiti pri uporabi EPR elementov. V drugem delu naloge so spoznanja iz prvega dela uporabljena na primeru analize poglobitve morskega dna iz 12 m na 15 m. V nadaljevanju je model z uporabo EPR elementov primerjan z modeliranjem kolov z linijskimi elementi in z modelom modeliranem v programu Phase 2.0.
