Do a Marmaray in Izmir Bay!

Assoc. Prof. Yücel has worked as a consultant for giant engineering companies around the world for 30 years. Dr. Isfendiyar Egeli, Izmir, Karsiyaka and Balçova districts planned to be made between the 7 thousand 580-meter gate, as in Marmaray Project should be done in the tube passage system, he said. Finding the project as a suspension or suspension bridge is extremely inconvenient Izmir Institute of Technology (IYTE) Faculty Member Egeli, 300 meters deep in the rocky area at the bottom of the sea, the bridge in case of a bridge in the space will remain in the feet every year will be sunk slowly.

The Ministry of Transport, Maritime Affairs and Communication for the planned passage to be made within the scope of the İzmir Highway and Rail Gulf Transit Project (İZKARAY), which has mega projects within the hazır 35 İzmir, 35 Project leşme promise of the AK Party government, is preparing a feasibility report for a company.

Assoc. Dr. Egeli, the ministry still can not make a decision, officials said that half of the tunnel, half hanging or hanging on the bridge passed. Egeli argued that the entire project should be an immersed tunnel like Marmaray, and described the two major risks in the bridges as 'unacceptable'.

Noting that the prefabricated units of the submerged tunnel would be pressurized, Egeli said: “Since it will be connected to the intersections on both sides, it will be a linear line between these points. This will ensure the best protection against an earthquake of magnitude 7 on the Richter scale and the watertightness of the tunnel during the earthquake. The same is true for bridges. Aynı


As stated in Marmaray, cement injection improvement should be done under the tube passage system. İsfendiyar underlined that since at least five ventilation chimneys will be made, it will be the most suitable solution for earthquake resistance and cheapest cost. Half of the immersed tunnel, Çiğli side of the suspension or suspension bridge will occur if there would be many disadvantages Egeli, ortalama dipping tunnel at the depth of about 15 meters from the sea bottom and the sea below the sea below the average 15 meter, considering that the bridges at least 70 meters above sea level, Since the maximum rail slope in the middle metro line is 100 (world standard) in order to close the 2,5 meter elevation difference, it is necessary to construct a ramp island with a minimum length of 4 in the middle of the İzmir Bay between the tunnels and the bridge. This leads to the rapid filling of the inner Gulf and is not acceptable. In this case, the 7,6 requires an 2 kilometer immersed tunnel in the south-wide Gulf wide south and the 1,6 kilometer-long bridge in the north. Bu


The depth of the Gulf of Izmir is not much, but the rock depth is different. Dr. Egeli, daj At Ataşehir Junction (front of Çiğli Kipa) is known from DLH sea drillings where the bedrock depth is around 250 a 280 meter. Both the suspension bridge and the suspension bridge will be pile under the pile. Even the longest pile of 100 meters will be suspended on the bedrock and will be buried even further in earthquakes. If there is improvement in the area around the stakes and bridge feet, the risk of large seating in the stakes is very high. Rope anchors on the suspension bridge is a problem, the situation is even more grave.


A tunnel like Marmaray Project is less costly. Egeli says that the immersed tunnel is estimated to be 3,6 billion dollars, the suspension bridge is 3,8 billion dollars and the suspension bridge option is calculated as 4,8 billion dollars cost.
