Engineering geological evaluation of the conditions for constructing a bridge and a tunnel in the zone of the old Petrovaradin Fortress, Serbia

Abstract

The paper discusses the geotechnical conditions related to the construction of a new bridge over the Danube and a tunnel passing beneath the Petrovaradin Fortress at Novi Sad, Serbia. Analyses showed that both the bridge and the tunnel could be built without causing damage to any of the historical structures and that it would better to build two 8 m wide tunnels than a single 16 m wide structure. One of the two tunnels will involve the widening of an existing one, whereas the other will be newly constructed. The evidence suggests that the new bridge can be built on the reinforced piers of a bridge which was destroyed in World War II.
