Abstract

U ovom diplomskom radu izraĎena su i analizirana varijantna rješenja podvodnog cestovnog tunela koji bi povezao otok Korčulu s poluotokom Pelješcem preko najuţeg dijela Korčulanskog kanala, na lokaciji Kneţe - rt Sv. Ivan, kako je definirano Prostornim planom Dubrovačko-neretvanske ţupanije. Varijantna rješenja obuhvaćaju pet različitih horizontalnih trasa cestovne prometnice treće kategorije, za koje je provedeno istraţivanje mogućnosti primjene tri različita tipa podvodnog tunela: uronjenog, plutajućeg i bušenog podvodnog tunela. Podvodni tuneli se u Hrvatskoj nisu primjenjivali u praksi kao rješenje prijelaza cestovnih prometnica preko vodenih prepreka, stoga su radu navedene njihove osnovne karakteristike te pozitivne i negativne strane gradnje ovakvih tunela. U radu su nadalje prikazane zajedničke karakteristike varijantnih rješenja s obzirom na horizontalne i vertikalne elemente, poprečni presjek, te potrebnu opremu i razinu sigurnosti. Varijantna rješenja su vrednovana te su istaknute njihove prednosti i mane s obzirom na opisane kriterije kako bi se utvrdilo koja je od njih optimalna u smislu geometrije trase i teţine izvedbe. Temeljem navedene analize zaključeno je da je najprikladnija varijanta u smislu poloţenih horizontalnih elemenata Varijanta 4 te unutar te varijante, kao optimalno pokazalo se rješenje za uronjeni tip tunela.

Abstract (english)

In this graduate thesis, variant solutions of the underwater road tunnel that would connect the island of Korčula with the Pelješac peninsula through the narrowest part of the Korčula channel, at the location Kneţe - cape Sv. Ivan, were designed and analysed. Variant solutions include five horizontal alignments of the third category road, for which a study of the possibility of applying submerged, floating, and bored tunnel was conducted. The basic characteristics of underwater tunnels and the positive and negative sides of their construction are listed. Variant solutions were compared concerning horizontal and vertical alignment elements, as well as standard cross sections. The necessary tunnel equipment and level of safety are also presented. Variant solutions were evaluated and their advantages and disadvantages are highlighted to determine which of them is optimal in terms of alignment geometry and construction possibilities. Based on this analysis, it was concluded that the most suitable variant in terms of horizontal alignment is Variant 4. Within this variant, the solution for the submerged type of tunnel proved to be optimal.
