With the increasing pace of urbanization, the use of metro lines as underground transportation systems has become more widespread. This development necessitates the consideration of the potential impacts that new constructions may have on tunnel systems in areas where metro lines are present. In this study, the structural effects of a proposed building and its associated retaining system to be constructed near the M9 Ataköy–İkitelli Metro Line were investigated through a static analysis approach. Numerical modeling methods were employed, taking into account ground conditions and structural loads. The influence of the structures on tunnel deformations and stress distributions within the tunnel lining was evaluated. The analysis results indicate that the presence of the building does not cause significant displacements in the metro tunnels or in the segmental lining system. Nevertheless, it is emphasized that applying similar analytical approaches to all future constructions in the vicinity of metro lines is of critical importance for developing construction strategies that do not compromise the safety and integrity of underground tunnel systems.

METRO HATTI YAKININDA İNŞA EDİLECEK OLAN YAPILARIN TÜNELLERE OLAN ETKİSİNİN İNCELENMESİ

Öz

Kentleşmenin artmasıyla birlikte metro hatlarının yer altı ulaşım sistemi olarak kullanımı yaygınlaşmıştır. Bu durum, metro hatlarının bulunduğu bölgelerde yeni yapılaşmaların tünel sistemleri üzerindeki etkilerinin dikkate alınmasını zorunlu kılmaktadır. Bu çalışmada, M9 Ataköy-İkitelli Metro Hattı yakınında inşa edilecek olan yapı ve iksa sistemlerinin mevcut tünel sistemine olan etkisi statik olarak incelenmiştir. Çalışma kapsamında zemin koşulları ve yapı yükleri dikkate alınarak sayısal analiz yöntemi kullanılmıştır. Yapıların, tünel deformasyonları ve yapısal gerilme dağılımlarına etkisi değerlendirilmiştir. Analiz sonuçlarında yapı etkisi sebebiyle metro hattı tünelleri üzerinde ve tünel segment kaplamasında önemli bir deplasman görülmemiştir. Bununla birlikte metro hatları çevresinde yeni yapılacak olan tüm yapılarda benzer analiz yaklaşımlarının kullanılması metro tünellerinin güvenliğini tehdit etmeyecek şekilde yapılaşma stratejilerinin geliştirilmesi açısından son derece önemli olduğu değerlendirilmektedir.
