Tünel yapımında, güzergâh boyunca yapılan arama sondajlarından elde edilen zemin ve kaya profilleri, yeraltı suyu durumu ve yapı elemanları değerlendirilerek tünel projeleri gerçekleştirilmektedir. Uygulamada bazen sondajlar göre öngörülen jeolojik kesitler ile tünel yapımı sırasında karşılaşılan yapısal elemanlar arasında farklılıklar olabilmektedir. Bu çalışmada Phases 2D programı ile T35-GT1 tüneli için modellenmiştir. Ankara-İstanbul Hızlı Tren Projesi için konvansiyonel yöntemle açılan T35-GT1 tüneli imalatında sayısal analizlerle tahmin edilen ve karşılaşılan deformasyon miktarları karşılaştırılmıştır. Çalışmanın sonunda süreksizlik özellikleri hesaba dahil edildiğinde gerçekleşen deformasyonlar ile sayısal analizde elde edilen deformasyonların birbirine çok yakın değerler verdiği sonucuna varılmıştır.

In tunnel construction, tunnel projects are carried out by evaluating the soil and rock profiles obtained from the exploration drillings along the route, groundwater status, and structural elements. In practice, there may sometimes be differences between the geological sections foreseen according to the exploration drillings and the structural elements encountered during tunnel construction. In this study were modeled for the T35-GT1 tunnel by Phases 2D program. For the Ankara-Istanbul High-Speed Train Project, the deformation amounts predicted by numerical analysis and encountered during the T35-GT1 tunnel manufacturing, opened by the conventional method were compared. At the end of the study, it was concluded that when the discontinuity properties are included in the calculation, the deformations realized and the deformations obtained in numerical analysis give values very close to each other.
