Abstract

U diplomskom radu je prikazano pet varijanti idejnog rješenja produžetka autoceste A1 Zagreb – Split – Dubrovnik na području Dubrovačko-neretvanske županije između Osojnika i Zarovca. Sve varijante projektirane su u skladu s važećim Pravilnikom (NN 110/01), te prostornim planom Dubrovačko-neretvanske županije. Varijante su projektirane za projektnu brzinu od 110 km/h i 130 km/h. Duljine dionica se kreću su između 4080.712 m i 4160.994 m. U horizontalnom smislu trase cesta se sastoje od 2 pravca i 4 ili 5 krivina. Polumjeri krivina se kreću od 1200 do 2000 m. U vertikalnom smislu trase ceste su definirane niveletom. Maksimalni primijenjeni uzdužni nagib iznosi 4 %, a minimalni 0.5 %. Poprečni presjek ceste sastoji se od dva kolnika razdvojena razdjelnim pojasom, svaki sa po dva prometna traka. U tri varijante širina prometnog traka je 3.75 m uz zaustavni trak širine 2.5 m. Dvije varijante projektirane su sa širinom traka 3.5 m. Na odabranim varijantama je ispitana preglednost u oba smjera. Rezultati ispitivanja su pokazali da uvjeti preglednosti nisu ispunjeni na određenom dijelu dionice te da je potrebno proširiti bermu. U sklopu projektiranja trase nove ceste predviđena je i rekonstrukcija postojeće županijske ceste Ž6235 uz izradu nadvožnjaka na istoj.

Abstract (english)

The master thesis presents five variants of the preliminary design of the A1 Zagreb - Split - Dubrovnik motorway in the area of Dubrovnik-Neretva County between Osojnik and Zarovac. All variants are designed in accordance with the valid regulation (Official Gazette 110/01) and the spatial plan of Dubrovnik-Neretva County. The variants are designed for a design speed of 110 km/h and 130 km/h. The length of the sections is between 4,080,712 m and 4,160,994 m. The horizontal alignment consists of 2 straight lines and 4 or 5 curves. The curve radii are between 1,200 and 2,000 m. The vertical alignment consists of straight lines and crest curves. The maximum longitudinal gradient is 4%, the minimum 0.5%. The cross-section of the road consists of two carriageways separated by a median, each with two lanes. In three variants, the lane width is 3.75 m with a 2.5 m wide stopping lane. Two variants were designed with a lane width of 3.5 m. Stopping sight distance was tested in both directions for the selected variants. The test results showed that the sight distance conditions were not met in a certain part of the section and the side slope had to be widened. As part of the design of the corridor of the new road, the reconstruction of the existing county road Ž6235 and the construction of an overpass are planned.
