Abstract

Idejnim rješenjem željezničke obilaznice naselja Bibinje na pruzi M 606 Knin - Zadar predviđena je izgradnja obilaznice u duljini od oko 6,7 km. Obzirom na vrlo zahtjevnu konfiguraciju terena u zaleđu naselja Bibinje dio trase obilaznice duljine 3 km nalazit će se u tunelu. U ovom diplomskom radu dan je prikaz postojećeg stanja pruge te su analizirana dva varijantna rješenja tunela Bibinje. Prva varijanta predviđa izvedbu jednokolosiječnog tunela sa kratkom servisnom cijevi koja je okomita na glavnu cijev te vertikalnog okna. Druga varijanta predviđa izvedbu jednokolosiječnog tunela sa dugom servisnom cijevi koja je paralelna na glavnu cijev. Zaključeno je da oba rješenja pružaju odgovarajuću sigurnost korisnika tunela u slučaju incidenta, kao što su požari ili druge havarije. Nakon ove analize varijante su valorizirane i temeljem investicijskih i operativnih troškova. Ta analiza je pokazala da je sa financijskog aspekta prikladnija varijanta jednokolosiječnog tunela sa kratkom servisnom cijevi koja je okomita na glavnu cijev te vertikalnog okna.

Abstract (english)

The preliminary design of the railway bypass of the settlement of Bibinje on the M 606 Knin - Zadar line envisages the construction of a bypass with a length of about 6.7 km. Considering the very demanding configuration of the terrain in the hinterland of the settlement of Bibinje, 3 km of this route will be in a tunnel. In this graduate thesis, the current state of the railway is presented, and two variant solutions of the Bibinje tunnel are analyzed. The first variant envisages the construction of a single-track tunnel with a short service tube that is perpendicular to the main tube, and a vertical shaft. The second variant envisages the construction of a single-track tunnel with a long service tube parallel to the main one. It was concluded that both solutions provide adequate safety for tunnel users in the event of an incident, such as fire or other accidents. After this analysis, the variants were valued based on investment and operating costs. That analysis showed that the variant of a single-track tunnel with a short service tube that is perpendicular to the main one and a vertical shaft is more suitable from a financial point of view.
