Seismic fragility and risk assessment of transportation tunnels in Marmara and Aegean regions of Turkiye.

ABSTRACT: Turkiye is located in the Alpine-Himalayan belt, one of the most active seismic zones in the world. In addition to these natural processes, the Marmara and Aegean regions of Türkiye have a very high population density. As a result of this situation, the transportation network in both regions is well developed, and there are many railway and roadway tunnels. However, the general seismic fragility of these tunnels has not yet been investigated. For this reason, the purpose of the study is to analyze the seismic fragility of the transportation tunnels in the Marmara and the Aegean regions of Türkiye. For the purpose of the study, the necessary information of the 184 tunnels was compiled and analyzed with the three well-established methodologies. The results were also checked by the April 23,
