Abstract

U ovom diplomskom radu su prikazane dvije varijante idejnog rješenja nove državne ceste DC12 Bjelovar - Virovitica na dionici Velika Pisanica - Sibenik čiji je trenutni status koridor u istraživanju. Varijante su projektirane u skladu s Pravilnikom (NN 110/01) za projektnu brzinu od 110 km/h. Duljina dionice za varijantu 1 iznosi 8323.792 m, a za varijantu 2 iznosi 8337.604 m. U horizontalnom smislu varijanta 1 se sastoji od četiri pravca, četiri krivina i prijelaznica. Varijanta 2 sastoji se od dva pravca, pet protusmjernih krivina i prijelaznica. Primijenjeni polumjeri krivina su od 1500 do 1900 m. U vertikalnom smislu trasa je definirana niveletom, pri čemu je maksimalni primijenjeni uzdužni nagib 1.09% za varijantu 1, odnosno 1.15% za varijantu 2. Najmanji primijenjeni uzdužni nagib u varijanti 1 iznosi 0.50%, a u varijanti 2 iznosi 0.53%. Niveleta je na lomovima zaobljena vertikalnim krivinama polumjera od 14000 do 22000 m. Kao mjerodavni poprečni profil odabran je profil 1-b (brza cesta, Vp=100 km/h) s dva kolnika i razdjelinim pojasom. Na projektiranim varijantama ceste ispitana je preglednost. Pokazalo se da brza cesta na nekim dijelovima ne zadovoljava uvjete preglednosti te da je potrebno proširiti bermu. Idejnim projektom obuhvaćena je izrada idejnih projekata rekonstrukcije jedne županijske i jedne nerazvrstane ceste koji se sijeku s trasom brze ceste.

Abstract (english)

The master thesis presents the preliminary design of two variants of the state road DC12 on the section between Velika Pisanica and Sibenik in the Bjelovar – Bilogora County. The road has been designed in accordance with the Croatian regulation (NN 110/01) and for a design speed of 110 km/h. The length of the designed road section is 8323.792 meters for variant 1 and 8337.604 metres for variant 2. The horizontal alignment of variant 1 consists of four straights, four curves and transitions. The horizontal alignment of variant 2 consists of two straights, five curves and transitions. The radii of the curves are between 1500 and 1900 metres. The vertical alignment of variant 1 has a maximum longitudinal gradient of 1.09%, that of variant 2 has 1.15%. The minimum longitudinal gradient is 0.5% for variant 1 and 0.53% for variant 2. In both variants, the planned road has two carriageways divided by a median, typical cross-section 1-b (1st road category for the design speed of 100 km/h). The stopping distance was also tested on the planned road. The test results showed that the required conditions were not met on the entire section and that the hard shoulder needed to be widened. As part of project assignment, two roads (county road and uncategorised road) were redesigned at the intersection with the planned DC12 road.
