13 Gülburnu Bridge

In scope of the construction of Gülburnu Bridge, crossing with an aesthetic bridge of the bay containing the historical Zefre Harbor and protection of Gülburnu Bay that has a natural beauty have been aimed. Desire of large span selection is closely related to geological and topographical features of the sea bottom.

The bedrocks are about 15 meters to 20 meters deep in the sea. Thus, they lead to reduce the number of pier as much as possible and place in shallower parts.

“Free balanced cantilever method” has been selected as a construction method because it is not possible to base scaffolding at offshore.

İdemli viaducts (1, 2.1, 2.2 and 3) have required a special structure design because of landslide having 20 m depth in the bridge area. A structure design has led to large spans without block of the landslide as much as possible. A composite superstructure has been selected consisting of four I-beams and cast in place deck because of ease of construction and road profile. The superstructure system is continuous.

165 cm diameter steel armored bored piles have been used to withstand landslide effects.

Esenler New Viaduct (Section 1 and 2) has been designed as a light rail transport system and construction has been stopped after some time. Seismic retrofitting has become a necessity because of insufficient pile, foundation and column capacities.

The construction siteis located on city center as a result all kind of excavation, forage and jacketing in the site may have caused traffic problems. In order to minimize such operations in both viaducts, seismic isolators have been used. In addition, concrete rail beam has been used instead of ballast to reduce the weight of the bridge superstructure.

The U – section is used to increase the torsional stiffness of the superstructure because of the horizontal curves with small radius. Difficulty of superstructure geometry has brought special solutions in the design.
