Yeraltı Raylı Sistem İnşaatlarındaki Jeoteknik İncelemeler ve Geoteknik Uygulamalar: Halkalı-Yeni Havalimanı Metro Hattı Örneği
Abstract
Bu çalışmada yeraltı raylı sistemleri inşası öncesinde gerçekleştirilen jeolojik araştırmalar ve inşası sırasında tercih edilen geoteknik uygulama yöntemleri Halkalı-Yeni Havalimanı metro projesi kapsamında incelenmiştir. Metro hattı 31,3×2 km ana hat, 1,8×2 km depo bağlantı hattı olmak üzere toplam 66,2 km uzunluğundaki yeraltı tünellerinden oluşmaktadır. Jeolojik araştırması toplam 9588,5 m uzunluğunda 198 adet karotlu sondaj ile gerçekleştirilen ana hat için 1006 adet zemin, 1230 adet kaya numunesi toplanmıştır. Numuneler üzerinde yapılan laboratuvar deneylerinin ve sondaj kuyularında gerçekleştirilen arazi deneylerinin sonuçları elde edilmiştir. Ayrıca TBM (Tünel Açma Makinesi) güzergahı iki hattın ortasında (Hat-1 Km. 61+440 – 61+660 / Hat-2 Km: 61+400 – 61+620), Olimpiyatköy Stadı istasyonunda (Km: 62+215 – 62+490) iki adet ve TBM güzergahında (Hat-2 Km: 62+835 – 63+050) olmak üzere Çoklu Elektrotlu Elektrik Özdirenç Tomografi ölçüm yöntemi kullanılarak toplam dört adet iki boyutlu ters çözüm özdirenç yeraltı kesiti elde edilmiştir. Sondajlardan elde edilen jeolojik kesitler ile elektrik özdirenç yöntemi ile elde edilen jeofizik kesitler karşılaştırılmıştır.

Geotechnical Inspections and Geotechnical Applications in Underground Rail System Constructions: Halkalı - İstanbul Airport Metro Line Example
Abstract
In this study, geological researches carried out before the construction of underground rail systems and geotechnical application methods preferred during the construction were examined within the scope of Halkalı-İstanbul Airport metro project. The metro line consists of a total of 66.2 km long underground tunnels, 31.3×2 km main line and 1.8×2 km repertorium connection line. 1006 soil and 1230 rock samples were collected for the main line whose geological research was carried out with 198 core drillings with a total length of 9588.5 m. The results of the laboratory tests on the samples and the field tests carried out in the boreholes were obtained. In addition, a total of four two-dimensional inverted solution resistor underground sections were obtained by using the Multiple Electrode Electrical Resistance Tomography measurement method in the middle of two lines (Line-1 Km. 61+440 – 61 +660 /Line-2 Km: 61 +400 - 61+620), in the Olympic Stadium station (Km: 62+215 – 62 +490) and in the TBM route (Line-2 Km: 62 +835 – 63+050). The geological sections obtained from the drillings and the geophysical sections obtained by the electrical resistivity method were compared.
