Mega projects are resistant to even the most severe earthquakes

Transport, Maritime Affairs and Communications Minister Ahmet Arslan, earthquake Yavuz Sultan Selim in Turkey is located in the zone and reported Osmangazi that bridge with Eurasia and even earthquakes in huge violence Marmaray tunnel like a giant structure of 2 thousand 500 years that may occur about once made and designed so that it can survive.

Minister Arslan, said in a statement, 18 years ago occurred and 17 century called the disaster 1999 August Marmara said they still feel the pain of the earthquake, Turkey is deeply shocking and affecting all citizens' lives 17 August earthquake, once again sadness at the anniversary and pain felt in their hearts that told.

Expressing that they have taken important lessons from this disaster with the pain experienced, Arslan said, ne Unfortunately, we witnessed first hand that not the earthquake but the poor quality buildings, poor quality buildings, poor quality bridges and tunnels. Being in the earthquake zone of our country requires us to learn to live with the earthquake and to be prepared for possible earthquakes at any time. That's why we build every tunnel, every bridge, every structure by keeping the earthquake factor at the forefront. ”

“Old bridges have been made earthquake resistant”

Armstrong, seismic zone located in Turkey as Yavuz Sultan Selim and Osmangazi bridges giant structures of all kinds of wind effects on as well as the construction of resistant severe earthquake resistant structures stressing that, "Last year we opened to traffic Osmangazi and Yavuz Sultan Selim bridge Our approximately 2 thousand 500 years It was designed to survive even in the event of a major earthquake that could occur. 15 July Martyrs Bridge and Fatih Sultan Mehmet Bridge have reached the equivalent seismic resistance with Osmangazi and Yavuz Sultan Selim bridges with the seismic and structural strengthening works performed according to the current specifications. ”

“Eurasia Tunnel, 7,5 moment earthquake resistant dayanıklı

Arslan underlined that giant projects such as Eurasia and Marmaray tunnels passing under the Sea of ​​Marmara will be one of the safest places in the possible earthquake in Istanbul and said:

“The Eurasia Tunnel is located 16 kilometers away from the North Anatolian fault line and has been designed with the largest earthquake possible once a year. With the earthquake loads, tsunami effects and liquefaction in mind, the tunnel was designed and manufactured according to the latest international standards and was constructed with two seismic seals according to an 2 moment magnitude earthquake that might be in the North Anatolian fault. Built under the Bosphorus, the system will be able to continue undamaged service even in an earthquake of the magnitude 500 once a year in Istanbul.

“Marmaray floor was built with earthquake rules”

Arsay explained that the design of the Marmaray Tunnel was made considering the possibility of breaking the 4 segment at the fault line at the same time and that such a break would create an earthquake of magnitude 7,5.

According to the fault map prepared after the 1999 Marmara earthquake, Arslan pointed out that the point where the closest fault passes to the tube tunnel is 16 kilometers away. he said.

Minister Arslan stated that Marmaray was built with the goal of zero security risk, minimum loss of function, immersion tunnel and water tightness in 7,5 moment magnitude earthquake and said, erken An early warning system was installed in the immersion tube tunnel in Marmaray. The system was set up to prevent trains outside the tunnel from entering the tunnel during and after the earthquake, and to ensure that trains in the tunnel were pulled to a safe location. Kul
