İMO Bursa Branch continues its technical trips to increase the professional development of its members and to see the exemplary projects on site. Members of the İMO Bursa Branch organized a technical trip to the 1915 Çanakkale Bridge construction site, which, when completed, will become the longest medium span bridge in the world. Civil engineers who visited the dry dock site in Gelibolu, where the caisson foundations were manufactured and constructed, were awarded with Public Private Partnership Bursa, Çanakkale Otoyol ve Köprüsü İnşaat Yatırım ve İşletme A.Ş. They were informed about the project with the presentation of Suspension Bridge Chief Kemal Çetin.
Suspension Bridge Chief Çetin explained the project's vision, tender information, project structuring, scope and highway bridge location. Emphasizing that the 1915 Çanakkale Bridge will be the longest medium span bridge in the world with a mid span of 2023 meters, Çetin said that the project, which is carried out with the Build-Operate-Transfer model, has completed the Malkara-Çanakkale stage, which has a total length of 88 kilometers, including 13 kilometers of main body and 101 kilometers of connection road.
Turkey's most developed and the population density is highest in the region to ensure uninterrupted access to the motorway network, the Aegean region in the sights rapid transport and agriculture activities To support projects carried out stated that Kemal Cetin, a project with an operating period of 16 years, the cost of 70 per cent noted that the lair was reserved for the suspension bridge.
IMPORTANT FOR WIND, CURRENT AND WAVE LENGTH CANAKKALE
Stating that the bridge was designed considering the climatic conditions, the current and wind factors in the sea, Suspension Bridge Chief Kemal Çetin said, “Çanakkale is a very windy place. The current and the wavelength affect us a lot, so we work by struggling with all these parameters and we plan to complete the bridge on the foreseen date. We conducted 3 tests on Çanakkale Bridge, two of which are tower and deck, one of which is full scale wind tunnel test. Wind; natural phenomenon whose behavior you could not predict. Important for such large structures. You are making calculations at the desk, but when you put it in the wind test, other things can come up, so the wind effect is a phenomenon that occurs with trial and error method and wind tunnel tests. "Wind tunnel tests affect the cost and health of the job," he said.
Explaining that they made an earthquake analysis in the area where the Çanakkale Bridge was built, although there was no earthquake risk like the Osmangazi Bridge, Çetin said that the ground was reinforced with steel piles against liquefaction.
THE WORLD'S ETRAFINI 4 CAN BE FILLED
Talking about the features of the main cable, Çetin said, “When you add each wire in the main cable, which consists of 144 wire bundles, to the end-to-end, you reach a length that will be wrapped around the world 4 times, which corresponds to 162 thousand 236 kilometers. Osmangazi Bridge corresponded to 80 thousand kilometers. Here it has doubled, ”he said.
Following the presentation, the members of the İMO Bursa Branch examined the caisson wells, which are currently under construction in the dry pool.
