Odabir između 2D i 3D numeričkog modeliranja ovisi prvenstveno o vrstiproblema koji se analizira, potrebama projekta, rokovima, dostupnim resursima teopravdanosti dodatnih ulaganja u složenije modele. U radu su prikazani rezultati2D i 3D numeričkih modela izvedbe dionice tunelske cijevi, kako bi se analiziraleosnovne razlike u dobivenim rezultatima i istaknule prednosti upotrebe 3D modela.Na temelju projektne dokumentacije, modeliran je poprečni presjek najnepovoljnijegprofila s najvećim nadslojem materijala. Analize su provedene u računalnimprogramima RS2 i RS3 tvrtke Rocscience. Rezultati su pokazali da je glavna prednost3D modela mogućnost praćenja povećanja radijalnih pomaka s napredovanjemiskopa te realnijeg uvida u efikasnost ugrađene podgrade. The choice between 2D and 3D numerical modeling depends primarily on the subjectanalysis, project requirements, deadlines, available resources, as well as justificationfor additional investment in complex models. The results of 2D and 3D tunnelnumerical models are presented in order to analyze the fundamental differences andto highlight the 3D model advantages. The models were created on the cross sectionwith the largest overlay, all according to the design documentation. The analyseswere performed using the RS2 and RS3 Rocscience programs. The obtained resultshave shown that the main advantage of the 3D model is the possibility to monitorthe increase of radial displacements with excavation progress, and to provide a morerealistic insight into the efficiency of the installed support elements.
