Abstract

U diplomskom radu su prikazane dvije varijante idejnog rješenja nove zagrebačke cestovne obilaznice na dionici Polonje-Vrhovec čiji je trenutni status koridor u istraživanju. Varijante su projektirane u skladu s Pravilnikom (NN 110/01) za projektnu brzinu od 130 km/h. Duljina dionice za varijantu 1 iznosi 9453.615 m, a za varijantu 2 iznosi 9208.128 m. U horizontalnom smislu varijanta 1 se sastoji od 2 pravca, 5 protusmjernih krivina i prijelaznica. Varijanta 2 sastoji se od 2 pravca, 4 protusmjerne krivine i prijelaznica. Primijenjeni polumjeri krivina iznose 900, 1500 i 2000 m. Vertikalno vođenje trase ceste definirano je niveletom, pri čemu je maksimalni primijenjeni uzdužni nagib 2.32% za varijantu 1 odnosno 1.76% za varijantu 2. Najmanji primijenjeni uzdužni nagib u obje varijante iznosi 0.5%. Niveleta je na lomovima zaobljena vertikalnim krivinama polumjera 30000 m. Kao mjerodavni poprečni profil odabran je profil A-a (autoceste, Vp≥120 km/h). Širine prometnih trakova su 3.75 m, zaustavnih trakova 2.5 m, rubnih trakova 0.2 m i 0.5 m te razdjelnog pojasa 4 m. Na projektiranim varijantama ceste ispitana je preglednost. Pokazalo se da autocesta na nekim dijelovima ne zadovoljava uvjete preglednosti te da je potrebno proširiti bermu. Idejnim projektom obuhvaćena je izrada idejnih projekata rekonstrukcije dviju županijskih cesta koji se sijeku s trasom. U vertikalnom smislu su nivelete županijskih cesta definirane kao nadvožnjak.

Abstract (english)

This master thesis presents two preliminary variants of the new bypass road around Zagreb between Polonje and Vrhovec, whose current status is a corridor in research. The variants are designed for a design speed of 130 km/h according to the Croatian regulation (NN110/01). The length of the designed road section is 9453.615 m for variant 1 and 9208.128 m for variant 2. The horizontal alignment of variant 1 consists of 2 straight lines, 5 curves and transition curves. Variant 2 consists of 2 straight lines, 4 curves and transition curves. The applied curve radii are 900, 1500 and 2000 m. The vertical alignment of the designed road has a maximum longitudinal slope of 2.32% in variant 1 and 1.76% in variant 2. The minimum longitudinal slope is 0.5% in both variants. Profile A-a (motorways with design speed ≥120 km/h) is chosen as the standard cross-section profile. The width of the lanes is 3.75 m, the width of the stopping lanes is 2.50 m, the width of the shoulder lanes is 0.2 m and 0.5 m, respectively, and the width of the median is 4 m. The stopping sight distance was examined on the designed road variants. Sight distance requirements were not met on some sections of the motorway so widening of the side slope is required on these sections. Reconstruction of the two existing roads that intersect with the designed motorway corridor is also part of the project scope, and their vertical alignment is defined as an overpass.
