Terrain drainage in the landslide area on the Danube slope in Novi Sad

Abstract

© 2015, Strojarski Facultet. All rights reserved. The landslide in the zone of the Sloboda Bridge in Novi Sad is one of the most extensively researched landslides in Serbia because it is large and it poses a threat to the stability of the aforementioned bridge over the Danube. At the time of its completion in 1981, this cantilever-spar cable-stayed bridge was the largest in the world, with a central span of 351 m. In the body of the landslide, the bridge is founded on reinforced concrete piles 27 m in length. The measured depth of movement for the first part of the sliding mass is 26 m, while that of the second one is 35 m. The designed drainage structures consist of the following: two wells with diameters of 6,5 m and depths of 22 m, eight drains with lengths of 45 m and a drainage tunnel linking the pressure chamber and the wells.
